A Experimental Study on NYAB Self-Doubling Laser Pumped by Laser Diode

研制出国内第一台用LD泵浦的NYAB自倍频激光器和双波长激光器。采用直接耦合方式进行端面泵浦。自倍频激光器产生0.531μm的绿色激光,基横模运转,阈值泵浦功率为14.31mW,输出功率达2.2mW,斜效率达2.1％。双波长激光器同时产生0.531μm的绿色激光和1.062μm的近红外激光,基横模运转,阈值泵涌功率力14.81mW,输出功率达9.2mW,斜效率达7％。

A LD pumped NYAB self-doubling laser and a LD pumped NYAB double wavelength laser have been developed. The pumping laser beams of LD are directly focused into the NYAB lasers with a focus system. For the fundamental transverse mode operation, the self-doubling laser generates 2.2mW output power at 0.531μm with threshould pumping power of 14.31mW, and its slope efficiency is 2.1％; the double wavelength laser generates 9.2mW output power at 0.531μm and 1.062μm with threshould pumping power of 14.81mW, and its slope efficiency is 7％。
