利用皮秒激光泵浦的Nd：YVO_4激光器，实现了1.5 μ m倍频光参量产生。在1571-1630 nm范围内获得了1.0 W的平均功率，对应于光-光转换效率和斜率效率分别为16%和23%。与有机非线性DAST晶体相结合的系统也产生了频率为3.2 THz的太赫兹波。(C)2011年美国光学学会
Dual-frequency MHz-repetition 1.5-mu m optical parametric generation is demonstrated from a tandem system pumped by a picosecond Nd:YVO4 bounce laser. An average power of 1.0 W is obtained over the range 1571-1630 nm, corresponding to an optical-optical conversion efficiency and slope efficiency of 16% and 23%, respectively. Terahertz-wave with a frequency of 3.2 THz is also generated from the system in combination with an organic nonlinear DAST crystal. (C) 2011 Optical Society of America
