Who Invented laser: Today we will read Who Invented laser. Charles, the inventor of laser rays, believed that atomic radiation could be absorbed as light, in the form of radio waves, or in the form of heat. This is absorbed in the form of tiny packets of energy, due to which atoms move from one energy level to a higher level. The atom excited in this way can automatically drop to a lower level. When he does this, his energy drains. This electromagnetic radiation is visible to us in the form of light. This is what happens every day in the sun as the higher energy-level atoms lose their energy and fall to the lower level thus producing energy and light. (Who Invented laser)
Charles Townes thought of it differently. In 1917 AD, Einstein had discussed the excitation emission of radiation. Charles decided to execute it himself. Charles eventually came to the conclusion that if one wanted smaller waves than vacuum tubes, one would have to use ‘readymade’ tiny devices called molecules and atoms.
Charles thought – ‘If work is done to excite radiation in an orbit of a specified measurement, then more powerful rays can be obtained.
After some time, Charles discussed this theory with his students at Columbia University and requested to suggest a name for these rays. Just what then? The students gave so many names that a new technology-vocabulary was formed. Among them a student had suggested the name – Major. It is an acronym for ‘Microwave Amplification by Stimulated Emission of Radiation’. The name ‘eraser’ was also spread on the basis of ‘infrared amplification’. (Who Invented laser)
A name for X-ray amplification was also proposed as ‘Exajar’. Ultimately, the name ‘Laser’ was chosen unanimously on the basis of light amplification. ‘Major’ and ‘Laser’ are still touching the heights of popularity.
When the name was chosen, the work began. A device for ‘Microwave Amplification’ ‘Microwave Amplification’ has been developed. Ammonia gas was chosen for its medium. Ammonia gas was chosen because it interacts quickly with microwaves.
James Gordon, a student along with a young physicist like Herbert Zeiger, was assigned this project for thesis. For three years, James worked with full devotion, dedication and diligence on the subject he met, and finally James’s hard work paid off. James was successful in showing the exact frequency produced by the vibrations of the molecules .
The pure frequency was assumed to be used as a fine-tuned clock. It is given for example that if we know that the frequency of the ray emerging from the source is sixty cycles per second, then it means that it will take sixty-sixth of a second to complete one cycle. There will be sixty cycles in one second and three thousand six hundred cycles will be completed in one minute. In this way, it is necessary to count cycles in order to make an accurate time clock.
In the year 1950, this type of Ammonia Major clock was made, with the help of which the exact time up to the billionth part could be known. Modern atomic clocks use the hydrogen measure and give accurate time calculations up to a hundred-trillionth. If these clocks keep running, they will make a difference of only one minute in millions of years.
Charles Hard Towns invented the laser beam in 1951 AD on a park bench. The park in which this miraculous ray was born is located in the city of Washington, D.C., United States. It was Franklin Square Park. (Who Invented laser)
It happened that in those days Charles was searching for a new technique of generating radio-waves. He was sitting on a bench in Franklin Square Park, admiring the beauty of nature. All of a sudden, the idea came to his mind that how to get the electromagnetic waves from the molecules?
It was this thought of Charles, which changed the nature of the twentieth century itself. Charles wanted to find radio waves of such high frequency, which could not be produced by the then vacuum tubes. Charles was sure that these high -frequency short waves would one day be helpful in microscopic measurements and analysis and would bring a great revolution in the field of physics and chemistry.
Finally the vision of Charles Hard Towns came true. The situation today is that laser rays are being used far more than Charles had imagined. These rays are also being extensively used in the field of medicine. Surgeons are using laser-rays to affix the cornea of the eye. Blood clots are also being dissolved with their help. Laser rays are being used to make fine-grained holes in metals.
The credit for advancing the communication revolution also goes to these laser rays. Many engineers related to communication technology, with the help of fiber optics, send a lot of information to thousands of kilometers away every day. Laser rays are being used to read the price of things in the supermarkets of developed countries. Many new challenges to the culture of space science have been solved by laser beams.

Actually laser rays are those invisible rays of energy, which are stimulated by the combination of three gases. Those three gases are helium, nitrogen and carbon-di-oxide. This is called a carbon-di-oxide laser. The laser produces microscopic rays and these rays have the ability to penetrate even diamonds.
The laser produces a high amount of instant light. Secondly, the laser is called ‘surgery numedinium’ part, but in ‘neurosurgery’ the carbon-di-oxide laser is mainly used.
The laser is loaded into a cylinder of gas, then brought into the ‘infratab range’ by a tube. This releases energy, which causes the molecule to ‘break down’. The light generated by the laser flows in a single direction , which travels as a thin beam. The laser instrument consists mainly of two parts-
(1) a source of power, (2) a substance that expands light.
Incandescent radiation occurs only when energy is produced with the molecule excited by the power source.
In 1957 AD, Charles Hard Towns focused his attention on light rays. Light rays have a frequency of ten thousand times higher than that of microwaves. At that time the question arose in front of Charles that how to make the necessary resonating chamber i.e. ‘Resonating Chamber’?
In that situation, Charles asked one of his acquaintances, Arthur L., working at Bell Laboratories. Asked for help from Shallow. Arthur helped as much as he could. Together they created a lamboter room, with mirrors at both ends. In 1958, both together published a research paper on this subject. As soon as the research was published, there was panic all over the world.
In 1960, Theodore H Maiman of the ‘Hughes Air Cafe Company’ made the first effective laser equipment.
Here Ali Jaran of Bell-Laboratory, William R. Bennett Jr. and Donald R. Heriot demonstrated another type of laser device. Maiman used a tiny cylinder of synthetic ruby instead of gas in his device. In this way, laser devices were soon made using a variety of things.
Laser rays are extremely powerful. The reason for this is that due to stimulated amplification, the energy is ‘attached’, that is, they accumulate in the same direction as the original ray. This property of the laser produced surprising results. One watt of light emitted by a laser is equal to that of a zero-watt bulb. When a one-watt laser beam was thrown towards the moon, it appeared on the television placed there, while there was no sign of the twinkling lights of the big cities.
The people of the United States of America are using some kind of laser rays in all fields of science, physics, chemistry, medicine, immunity etc. There laser rays help in transmitting long distance telephone-calls. They print most of the hard copies of the computer, read the digital code of compact discs on the stereo system. Invented by Arthur Scallow and Charles Townes at Bell Telephone Laboratories in New Jersey only sixty years ago , this laser has developed into a tool without which life of high technology cannot be imagined.
It would not be an exaggeration to say that the first impact of the laser was on the field of scientific observation. This provided researchers with a beam of light that could not only identify molecules and atoms, initiate chemical processes, but also identify, measure, and modify the basic characteristics of ‘matter’. . Soon lasers were used industrially to cut objects and heat them. Whether it is cutting an iron shield with a powerful carbon-di-oxide laser or cutting an expensive synthetic fabric with a tiny laser held in your hand, all of these things are done very beautifully. Were.
Not only this, it is also being used in the world of music and entertainment. The mega-travel of gorgeous music is erupted and transmitted with the aid of a laser reader in the compact disc of a home-playable home stereo system. Similarly, this laser transfers the science information stored on the discs inside the computers to the paper quickly without any mistake. Many reports, memos, periodicals are now printed on computers using laser printers.
The most miraculous uses of laser are in the field of medicine. eyes by laser today
No one is unfamiliar with the surgery to be performed. About nine million people in India are blind and about 4.5 crore people are partially blind. This condition has made the task of prevention of blindness extremely challenging. About forty-five percent of cases of eye disorders are of ‘cataract’. The treatment of this disease has been done only by surgery , but the treatment of blindness arising from a disease like ‘glaucoma’ has not been discovered yet.
With the modern system of science ‘laser therapy’, it has become possible to prevent blindness even in terrible diseases like glaucoma. Black glaucoma is a dreadful disease, in which water gets accumulated inside the eyes and pressure starts building on the eye, as a result this pressure affects the various layers of the eye. In the treatment of this disease, the water stored inside the eye is removed by making a hole through laser rays. The patient gets relief by removing the water.
In the disease of glaucoma, the patient is not even aware and gradually the patient’s eyesight goes away, but the laser method has made the treatment of this disease very easy now.
Due to diabetes, the diabetic patient, due to the closure of the microscopic blood vessels in the eyes and pressure on them, caused the blood to accumulate on the sensitive retina, becoming a victim of blindness.
But, even in the treatment of this disease, the blood-veins of the patient are closed by laser rays, so that there is no flow of nutrients in the blood. Apart from this, laser rays are used to make the surface of the curtain alive by delivering more nutrients to it.
At the same time, laser-rays are used like welding in diseases of blood vessels, which burst due to disease, or are about to burst. Torn blood vessels are welded together by laser beams. Along with this , laser rays are also used in the disease of reduced eyesight. This disease is usually due to increasing age. The lasers used in all these diseases are called ‘organs’ and ‘krypton’ lasers.
Laser rays can be seen with the eye. The seven colors of the rainbow are blue, red and green.
In the modern scientific age, now a special type of laser ‘ND. Yag is being used to cut the membrane behind the pupil of the eye. These membranes often emerge after a cataract operation.
These membranes can be cut without surgery with the help of a laser. Earlier these membranes had to be removed by inserting tools inside the eye, but with the help of laser this task has become easier. This is the reason why the lost light of the eye is returned by cutting the membrane within a few minutes.
In fact the laser beam has brought a ray of light to many types of eye patients. The use of laser rays has started getting benefits in many diseases of the eye.
The formation of spots on the screen due to glaucoma, diabetes, which we call diabetes, diseases of the blood vessels on the screen of the eye, lack of nutrients on the sensitive screen due to blockage of the blood vessel and the formation of membrane behind the pupil. Including going etc. The use of laser rays in the treatment of glaucoma will be considered a leap of science. This method also reduced the complications in the treatment of eye disorders.
Earlier, deep digging, soldering and very fine work of earthworks were done with heavy machinery; There was a lot of difficulty then. But since the ‘laser ray’ has been discovered, everything has become easier.
Diamond is the hardest material in the world, but it is cut like a soft object by ‘laser rays’. Its rays have proved to be very useful in the excavation of tunnels.
The laser rays are so fine that they can pierce even the hair.
Apart from this, laser rays are also helpful in communication, sailing, search-news etc. From space travel to very dangerous surgeries, which are measured very carefully, these rays are done.
Today’s scientists want to do something for the blind with the help of these rays. These rays are proving helpful in providing eyes for the blind. A clock influenced by laser rays has been designed, with the help of which blind people can walk. By the magic of these clocks, blind people will be fully aware of the surrounding environment. This is helping the blind people a lot.
Burn wounds are also treated with laser rays. Doctors have successfully treated one wound after another.
