Laser
Is an acronym for Light Amplification by Stimulated Emission
of Radiation. A laser is a cavity, with mirrors at the ends,
filled with material such as crystal, glass, liquid, gas or
dye. It is a device that produces an intense beam of light
with the unique properties of coherence, collimation
and monochromaticity.
Laser Cutting
Manufacturing and fabricating process which uses an industrial
laser to cut materials, often metals. Metals able to be cut
by the laser cutting process include mild
steels, aluminum, stainless
steels, aerospace alloys, and coated
steels.
Laser Cutting Grade Steels
Types of steels specifically produced by steel manufacturers
for laser cutting applications. Laser cutting grade steels
have the same strength as standard materials, but contain
lower levels of impurities such as silicon and sulphur. These
steels can be cut at higher speeds and can be cut to a greater
maximum thickness.
Laser Generated Air Contaminants (LGAC)
Cutting with CO2 lasers
may produce air contaminants such as smoke, fumes, mists,
gases and/or vapors. Some particles may be toxic, mutagenic,
and be known carcinogens depending on the material cut.
Laser Oscillation
The buildup of the coherent wave between laser cavity end
mirrors. In CW mode,
the wave bounding back and forth between mirrors transmits
a fraction of its energy on each trip; in pulsed operation,
emission happens instantaneously.
Laser Product
A legal term in the U.S. See 21 CFR 1040.10, a laser or laser
system or any other product that incorporates or is intended
to incorporate a laser or a laser system.
Laser Safety Officer (LSO)
One who has authority to monitor and enforce measures to
the control of laser hazards and effect the knowledgeable
evaluation and control of laser hazards.
Lens
An optic (either reflective or refractive) that causes rays
of light to converge to a point. A lens is the optic used
to focus a laser beam on the workpiece. Short focal length
lenses provide narrow beam convergence angles, necessary to
penetrate thick metal sections. Beam
diameter is an important consideration in lens selection.
Power density and depth of focus can change with differing
beam diameters.
