项目摘要
The purpose of the research is to develop a compact opitical parametric oscillator (OPO) with LD (laser didode) -pumped microchip lasers and a new nonlinear crystal of CLBO (CsLiB_6O_<10>). In the final year, the OPO in UV region was tried to pump by fourth harmonic of the Nd : YAG and Nd : YVO_4 laser.(1) As the OPO pump source, the LD-pumped Nd : YVO_4 microchip green laser with intra-cavity SHG has been developed and single frequnency, high peak-power oscillation of 1.5kW was generated in green beam by using a KTP E/O Q-switch and a coupled cavity resonator. Basic design principle of the LD-pumped solid-state lasers was developed and reported in detail.(2) High power UV beam of 1 W average power at 266 nm has been generated with the fourth harmonic of the Nd : YAG laser using the CLBO crystal, and two times higher conversion efficiency was obtained than with the conventional BBO crysta.(3) Tuning range of the compact CLBO-OPO was analyzed with the phase matching condition using the Sellmeier equation of the CLBO crystal. The analysis shows that the OPO is widely tunable of about 1 PHz (1015Hz, wavelength range is : 270-2,700nm). In the OPO experiment, the damage threshold of the CLBO crystal was less than 100MW/cm^2 and no stable oscillation was realized by the optical damage.
本研究的目的是研制一种小型的LD泵浦微片激光器光学参量振荡器(OPO)和一种新型的非线性晶体CLBO(<10>CsLiB_6O_2)。最后一年,我们尝试了用Nd:YAG和Nd:YVO_4四倍频激光泵浦紫外光OPO。(1)作为OPO泵浦源,研制了LD泵浦的腔内二次谐波Nd:YVO 4微片绿色激光器,采用KTP电光调Q开关和耦合腔谐振器,在绿色光束中产生了1.5 kW的单频、高峰值功率振荡。详细介绍了LD泵浦固体激光器的基本设计原理。(2)用CLBO晶体作为Nd:YAG激光器的四倍频光源,获得了平均功率为1 W、波长为266 nm的高功率紫外光,其转换效率比普通BBO晶体提高了2倍。(3)利用CLBO晶体的Sellmeier方程,结合相位匹配条件,分析了紧凑型CLBO-OPO的调谐范围。分析表明,该OPO具有约1 PHz(1015 Hz,波长范围:270-2,700 nm)的宽调谐范围。在光学参量振荡实验中,CLBO晶体的损伤阈值小于100 MW/cm ^2,没有通过光损伤实现稳定振荡。
