Description:
YAG laser was born in the 1960s, with the development of
solid-state laser technology, people began to look for better
quality laser crystal materials. YAG (Yttrium aluminum garnet)
crystal is an ideal laser crystal material because of its excellent
physical and chemical properties. YAG lasers are usually Nd: YAG or
Yb: YAG, where Nd and Yb are chemical symbols for neodymium and
ytterbium, representing neodymium-doped and ytterbium-doped YAG
lasers, respectively. The important parameters of YAG laser include
output power, laser wavelength, pulse width, pulse repetition
frequency, etc. Among them, the output power determines the energy
of the laser, the laser wavelength determines the color and
transmission performance of the laser, and the pulse width and
pulse repetition frequency determine the pulse characteristics of
the laser.

Applications:
The working principle of YAG lasers is based on the theory of
stimulated radiation. When the YAG crystal is excited by an
external light source, the neodymium or ytterbium ions in the
crystal will be excited to a high energy level, and when these ions
return to a low energy level, they will emit a laser. YAG lasers
are widely used in industrial, medical, scientific research and
other fields. In the industrial field, YAG lasers are often used
for welding, cutting, marking, etc. In the medical field, YAG laser
is often used in eye surgery, cosmetic skin, etc. In the field of
scientific research, YAG lasers are often used for spectral
analysis, optical measurement and so on. With the development of
science and technology, the performance of YAG lasers will be
further improved, and the application field will be further
expanded. Future YAG lasers will be more compact, intelligent and
environmentally friendly. At the same time, with the development of
new materials and new processes, the manufacturing cost of YAG
lasers will be further reduced, so that more people can use YAG
lasers.
