AI Overview
Optically triggered Cr:YAG Q-switching uses an external laser diode to directly bleach a Cr:YAG saturable absorber in a Nd:YAG laser, enabling precise pulse timing control. By bleaching a thin sheet within the absorber perpendicular to the laser axis, this method reduces pulse-to-pulse timing jitter significantly, for instance, from 100 ns to 8 ns.

Is Q-switched ND Yag laser treatment safe?
However, most Q-Switched lasers also have a KTP filter that frequency-doubles the light into the 532 nm wavelength. This makes the Q-Switched Nd: YAG laser essential in the treatment of skin pigmentation. The pulse delivered by the laser is powerful enough to destroy its target, without harming surrounding skin.Jan 13, 2026
