Passive Q-switch crystals (saturable absorbers) generate short, high-peak-power pulses without external drive electronics. AOG CRYSTAL offers Cr4+:YAG (the standard saturable absorber for 1 micron Nd lasers), Co:Spinel (ideal for eye-safe 1.5 micron Er lasers), V:YAG (for 1.3 micron), and Cr:GSGG — available with AR coatings and in mounted or unmounted form, with custom apertures for microchip and pulsed lasers.
