Laser Terms Glossary

L

Lamp Excitation
A method that uses a lamp to excite the laser-medium of a solid-state laser.
Laser
Click here for details
An abbreviation which means, "Light Amplification by Stimulated Emission of Radiation".
Lasers have the following qualities:
(1) Monochromacity - A pure, single wavelength of light.
(2) Excellent directionality - A parallel beam that advances without spreading.
(3) High coherence - Uniform light phases.
Laser Diode
Lasers created using semiconductor materials as a whole.
Laser Medium

The source material that produces a gas or solid-state laser beam.
For each type of source material, it is possible to extract laser beams with different characteristics.
Laser Processing
Click here for details
Processing performed using a laser beam.
Primary applications include micro-processing, welding, marking, and cutting.
Laser Safety Goggles
Protective equipment that is used to protect the eyes from laser beams.
To select the best goggles, it is necessary to select a pair that matches the wavelength of the laser that will be used.
Laser Trimming
A working process where resistor materials are trimmed to regulated resistance values.
LD
See "Laser Diode"
LD PUMPING
A Laser Diode is used to excite the crystal in order to generate the laser light.
Longitudinal Mode
A state where laser beams of many frequencies are oscillated depending on the distance between the resonator mirrors.
