The Townes-Schawlow proposal led several groups to try building a laser. The Gould proposal became the basis of a classified military contract. Success came first to Theodore H. Maiman, who took a different approach at Hughes Research Laboratories in Malibu, California. Red (660, 635nm), green (532, 520nm), and blue (445, 405nm) lasers A laser is a machine that makes an amplified, single-color source of light. It uses special gases, liquids, or crystals to make the light with only a single color. The gases are energized to make them emit light. Then mirrors are used to amplify (make stronger) the light. A laser can be made so all the light travels in one. Before going into how LASER (Light Amplification by Stimulated Emission of Radiation) works, let’s first take a look at how light works. What is Light? Light is a kind of energy released by an atom. Light is made up of very small particles called photons. Atoms are the basic units of matter. Each atom consists of a nucleus and a set of electrons orbiting the nucleus. Nucleus is formed as a. Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align.

This is a list of laser types, their operational wavelengths, and their applications. Thousands of kinds of laser are known, but most of them are used only for specialized research. In the 1960s physicists at the Lawrence Livermore National Laboratory in California calculated that intense laser pulses could produce those conditions by heating and compressing tiny pellets containing mixtures of hydrogen isotopes. The first chemical laser was demonstrated in 1965 by Jerome V. V. Kasper and George C. Pimentel at the University of California, Berkeley. It was a hydrogen chloride laser operating at 3.7 micrometers. The letters in the word laser stand for L ight A mplification by S timulated E mission of R adiation. A laser is an unusual light source. It is quite different from a light bulb or a flash light. Lasers produce a very narrow beam of light. This type of light is useful for lots of technologies and instruments—even some that you might use at home! How does a laser work? Light travels in waves.
