用全波片实现473nm蓝光激光器的稳定运转
Stable Operation of 473 nm Blue Laser Using a Full-Wave Plate
【摘要】 报道了一种利用Ⅰ类临界相位匹配倍频晶体LBO的偏振器作用与石英晶体全波片的组合构成双折射滤光片的结构 ,获得了激光二极管 (LD)抽运Nd∶YAG/LBO蓝光激光器的稳定运转 ,在注入抽运功率为 1 2W的条件下获得了 2 5mW稳定的单频 4 73nm蓝光输出
【Abstract】 A kind of birefringent filter based on the combination of the polarization function of the type Ⅰ critical phase matching doubling frequency crystal LBO (LiB 3O 5) and the quartz full wave plate is presented. The stable operation of laser diode (LD) pumped Nd∶YAG (Nd∶Y 3Al 5O 12 )/LBO blue laser is obtained. When the pumping power input into Nd∶YAG is 1 2 W, 25 mW 473 nm blue laser with single longitudinal mode is obtained.
