What
Is Laser Technology?
LASER is an acronym for Light Amplification
by Stimulated
Emission of Radiation, a process by which
the laser generates a coherent optical beam that has
an essentially constant
wavelength. This wavelength varies depending on the type
of laser. There are many types of lasers for different processes,
with varying power output capabilities. The most popular
laser machines in the industry are CO2 and
Nd: Yag.
This
is a solid-state laser, which uses a transparent solid substance
as the active medium. The most common solid-state laser in
industrial application is the Neodymium-Doped
Yttrium-Aluminum-Garnet laser, commonly referred to as
the Nd: YAG laser. The Nd:
YAG is used as the host crystal because it has relatively
high thermal conductivity, high mechanical strength, good
optical quality, and it can be grown in large sizes. Because
the 1.06 um light from the Nd: YAG is transmitted
easily through flexible quartz fibers, system design can
be considerably
simpler than with CO2 Lasers. In addition, the Nd:
YAG wavelength is absorbed more
readily by metals than CO2 laser radiation,
further improving process efficiency.

Nd: YAG laser beam welding allows for extremely narrow welds
with minimal shrinkage and distortion. |
