What is a laser and how does it work?

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation.

What does 'laser' mean?

You'll often read in books that "laser" stands for Light Amplification by Stimulated Emission of Radiation. That's a complex and confusing mouthful but, if you pull it apart slowly, it's actually a very clear explanation of how lasers make their super-powerful beams of light. Let's start with the "R" of laser: radiation.

Why are lasers used in industrial applications?

In industrial applications, the laser wavelength is chosen so that it best interact with a given material type. A laser is a device that generates coherent light radiation that is spatially and temporally controllable. Lasers have many advantages compared to other sources of light.

What type of light does a laser produce?

A laser normally produces a very narrow beam of light in a single wavelength, in this case, green. Modern physics describes light and other forms of electromagnetic radiation as the group behavior of fundamental particles known as photons.

How are lasers characterized?

Lasers are characterized according to their wavelength in a vacuum. Most "single wavelength" lasers produce radiation in several modes with slightly different wavelengths. Although temporal coherence implies some degree of monochromaticity, some lasers emit a broad spectrum of light or emit different wavelengths of light simultaneously.

What are the applications of laser technology?

Lasers are also used in many surgical procedures such as LASIK eye surgery. In manufacturing, lasers are used for cutting, engraving, drilling and marking a broad range of materials. There are many applications for laser technology including the following:

What does laser mean?

The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.
