1064nm AR Coating Passive Q Switch Cr4+:YAG Laser Crystal
Cr4+: YAG Crystal is an excellent crystal for passively Q-switching
diode-pumped or lamp-pumped Nd: YAG, Nd: YLF, Nd: YVO4 or other Nd
and Yb doped lasers at a wavelength from 0.8 to 1.2 µm. Passive
Q-switches or saturable absorbers provide high power laser pulses
without electro-optic Q-switches, thereby reducing the package size
and eliminating a high voltage power supply. Cr4+: YAG is more
robust than dyes or color centers and is the material of choice for
1 µm Nd lasers.
Advantages
1. High chemical stability and reliability
2. Being easy to be operated
3. High damage threshold (>500MW/cm2)
4. As high power, solid-state and compact passive Q-Switch
5. Long lifetime and good thermal conductivity
Applications
1.Passively Q-switched lasers for laser rangefinders, LIDAR and
LIBS systems
2.Laser systems where short pulses are required.
