Diode Pumped NYAB Green Laser

Solid state minilaser sources are receiving increased attention because of the wide variety of space applications they could open up. LaserGenics will investigate the self-frequency-doubling crystal NYAB. This material could lead to a compact high power green laser that could be ideal for topographic mapping, as it can be readily Q-switched, is more efficient at high peak powers, and the 532 nm wavelength has a high detectivity. The only commercially available miniature solid state green laser is the diode pumped Nd:YAG laser with intracavity frequency doubling KTP as the nonlinear optical material; however, these systems are complicated. Previous LaserGenic experiments have demonstrated a self-frequency-doubled NYAB laser with 35 mW of green output. This project will further improve the laser, measure its output characteristics, and develop a high power Q-switched device.
