中文摘要:
报道了1064nm单频激光抽运的KTP晶体外腔单谐振光参量振荡器(OPO),获得了波长为2.05μm的纳秒激光脉冲输出。在平-平腔中,将2块II类相位匹配KTP晶体按走离补偿方式放置,在400 Hz重复频率下,抽运单脉冲能量达到5mJ时获得了单脉冲能量为0.9mJ的2.05μm信号光输出,其脉宽约为3.7ns,对应抽运光-信号光转换效率约为18%,光束质量因子M~2在x、y方向分别为2.08、3.03。

英文摘要:
A KTP crystal extra-cavity single-resonant optical parametric oscillator (OPO) pumped by 1064 nm single-frequency laser is reported, and the nanosecond laser pulse output with wavelength of 2.05 μm is obtained. In the plane-parallel cavity, two type II phase-matched KTP crystals are placed in walk-off-compensated mode. When the pump single pulse energy reaches 5 mJ at repetition frequency of 400 Hz, a 2.05 μm signal laser output with single pulse energy of 0.9 mJ is obtained, whose pulse width is about 3.7 ns, the corresponding conversion efficiency is about 18% from pump light to signal light, and the beam quality factor M2are 2.08, 3.03 in x, y directions, respectively. ? 2016, Chinese Lasers Press.
