采用300 W二极管阵列泵浦Nd：YAG板条作为有源介质，Cr：YAG作为被动Q开关，构建了基于KTP晶体的内腔式光参量振荡器（IOPO）。在1572 nm波长的1.9 mJ能量的信号脉冲被证明。在腔中，优化相对于单脉冲能量，相对于1064 nm泵浦辐射的信号脉冲持续时间缩短了五倍。与没有IOPO的相同腔中的泵浦激光器相比，实现了650 kW的信号峰值功率的两倍。的转换效率为44%，相对于1064 nm的泵浦光和3.8%，相对于二极管泵浦能量被证明。
An intracavity optical parametric oscillator (IOPO) based on bulk KTP crystal was constructed with a Nd:YAG slab as an active medium pumped by a 300-W diode array and Cr:YAG as a passive Q-switch. A signal pulse of 1.9-mJ energy at 1572-nm wavelength was demonstrated. In the cavity, optimized with respect to single-pulse energy, a five-fold shortening of signal-pulse duration with respect to 1064-nm pump radiation was observed. A twice as large level of signal peak power of 650 kW, compared to the pump laser in the same cavity without the IOPO, was achieved. A conversion efficiency of 44% with respect to the 1064-nm pump beam and 3.8% with respect to diode pump energy was demonstrated.
