Lasers are devices that emit light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
The term “LASER” is an acronym for “Light Amplification by Stimulated Emission of Radiation”
Laser light does not exist in nature. Only human technology can create laser light.
Unlike a regular light source, light from a laser contains exactly one color (wavelength) rather than a lot of different wavelengths. Laser light is therefore “monochromatic,” meaning of one color.
Laser light beams are very narrow and can be concentrated on one tiny spot. Laser light therefore is ‘collimated’.
Laser has a number of very special properties:
These properties make laser light very interesting for a range of applications.
Lasers are also finding many new uses in space missions. Lasers can be used in a device called a spectrometer.
A spectrometer uses light to identify the chemical composition of matter. As light passes through a gas, the gas soaks up certain colors, or wavelengths, of light. Different gases absorb different wavelengths. So the light that comes out the other side of a gas cloud will have a unique “fingerprint.” A spectrometer can read that fingerprint and identify the gas.
