报道了一种基于布儒斯特角三硼酸锂晶体的高功率全固态同步泵浦光参量振荡器的性能。泵浦方案包括一个二极管泵浦的放大级，以提高平均输出功率从一个附加的脉冲锁模Nd：YLF激光器的一个因素2。外部谐振倍频器效率的提高在523.5 nm处产生了660 mW的有用输出功率，用于泵浦光学参量振荡器。三硼酸锂晶体的温度调谐非临界相位匹配允许在0.65-2.7 μ m的范围内产生连续可调谐的辐射，在标准X-折叠谐振器中信号（空闲）的平均输出功率高达210 mW（110 mW）。谐振信号波的高腔内功率引入了发射脉冲的非线性啁啾。利用棱镜提供腔内色散补偿，产生了持续时间为1.63 ps的近变换极限脉冲，平均输出功率高达140 mW，即，峰值功率接近700 W。(C)1995年美国光学学会
The performance of a high-power all-solid-state synchronously pumped optical parametric oscillator based on a Brewster-angled lithium triborate crystal is reported. The pump scheme includes a diode-pumped amplifier stage to boost the mean output power from an additive-pulse mode-locked Nd:YLF laser by a factor of 2. Improvements in the efficiency for an external resonant frequency doubler have produced a useful output power of 660 mW at 523.5 nm for pumping the optical parametric oscillator. Temperature-tuned noncritical phase matching of the lithium triborate crystal permitted generation of continuously tunable radiation over the range 0.65-2.7 mu m with mean output powers for the signal (idler) as high as 210 mW (110 mW) in the standard X-fold resonator. The high intracavity power of the resonated signal wave introduced nonlinear chirping of the emitted pulses. With prisms to provide intracavity dispersion compensation, nearly transform-limited pulses of 1.63-ps duration were generated with mean output power of as much as 140 mW, i.e., peak powers of similar to 700 W.
