| 摘 要： | 利用电光调Q的Nd:YAG激光器抽运非临界相位匹配(θ=90°,φ=0°)环形腔KTP光学参变振荡器(OPO),实现了高能量人眼安全波段的1.57μm激光输出。理论与实验结果表明,减小谐振腔长度和注入种子源激光可以有效降低阈值,提高输出能量。当Nd:YAG激光器抽运能量为88mJ时,注入种子源功率由0mW增加到6mW,输出能量由8.8mJ增加到14mJ。当抽运能量为167.7mJ,注入种子源功率达到6mW时,最大输出能量达到46mJ,峰值功率7.44MW。 |

| Abstract: | An eye-safe laser source at 1.57 μm is demonstrated by using a non-critically phase-matched (θ=90°, φ=0°) ring cavity optical parametric oscillator pumped by an electro-optic Q-switched Nd:YAG laser. Theoretical and experimental results show that reducing the cavity length and injection of seed laser can effectively reduce the threshold, and increase the output energy. When the Nd:YAG laser energy is 88 mJ and the injected signal power changes from 0 to 6 mW, the output energy is enhanced from 8.8 to 14 mJ. When the pump energy is 167.7 mJ and the injected signal power is 6 mW, the maximum output energy of 46 mJ is obtained, corresponding to the peak power of 7.44 MW. |
