摘要
报道了用国产 L D泵浦 Nd∶YVO4产生的 1.34 2 μm的输出。首次用 类临界位相匹配 L BO腔内倍频实现了 6 71nm的红激光输出。当泵浦注入功率为 80 0 m W时 ,倍频红激光基模输出为 5 2 m W,光光转换效率达 6 .5 %。光束经扩束准直后测得偏振比高于 10 0∶ 1。在输出功率为 40 m W时 ,48h连续工作稳定性优于± 2 %
A design of LD pumped high efficiency Nd∶YVO 4/LBO red laser is reported in this paper Using type Ⅱ phase matching LBO for the first time, red laser at 671nm is obtained by 1 342μm intracavity double frequency When power of incident pump laser is 800mW, 52mW TEM 00 mode red laser is obtained, and the efficiency of optical to optical conversion arrives at 6 5% Measurement result shows that beam's polarization degree is more than 100∶1, and the instability of the power in 48 hours is better than ±2% at 40mW
