摘要
使用蓝光激光二极管抽运掺镨氟化钇锂（PrYLF）块状晶体，获得最大输出功率为166.6 mW的σ偏振607.4 nm连续橙光输出。通过在谐振腔中插入厚度为0.1 mm的玻璃薄片，并适当调节角度，获得了π偏振604.6 nm连续橙光输出，最大功率为60.6 mW，斜效率达到13.6%。通过进一步调节玻璃薄片的插入角度，进而获得了607、604、640 nm的多波长同时激射。
Abstract
A maximum output power of 166.6 mW at 607.4 nm (σ polarization) is achieved in bulk PrYLF laser crystal pumped by blue laser diode (LD). An operation of 604.6 nm (π polarization) laser with maximum output power of 60.6 mW and slope efficiency of 13.6% is got by inserting a 0.1 mm glass plate into the laser cavity as frequency selector. Simultaneous multi-wavelength emissions at 607, 604, and 640 nm are also obtained.
