Chromium-doped yttrium aluminum garnet (Cr4+:YAG) crystal is a very good passive Q-switching material with an application band of 0.8μm~1.2μm. The pulse width of the passive Q-switching YAG laser can be as short as 9ns, and the repetition frequency of the diode-pumped Nd:YVO4 can reach 10kHZ
Main features:
High chemical stability and reliability
Long life and good thermal conductivity
High laser damage threshold (>500MW/cm2 ) As a high-power, solid-state and compact passive Q-switch
Easy to operate
Typical applications:
Passive Q-switching
