We have constructed an optical parametric oscillator to generate 75-ps near-transform-limited pulses with wavelengths tunable about 1.053 µm for use in pump-probe studies of self-focusing. The singly resonant oscillator uses a Brewster-cut LiB(3)O(5) crystal that is oriented for type-II phase matching and synchronously pumped by the amplified and frequency-tripled pulse trains from a mode-locked and Q-switched Nd:YLP laser. An intracavity Pockels cell is used to switch out single 0.5-MW pulses at rates of 1 to 10 Hz. The design, construction, and performance of the oscillator are discussed. Measured performance is compared with design predictions and with detailed numerical simulations.
我们构建了一个光学参量振荡器，以产生75皮秒的近变换极限脉冲，其波长可在1.053微米附近调谐，用于自聚焦的泵浦 - 探测研究。单共振振荡器使用布儒斯特切割的LiB(3)O(5)晶体，该晶体用于II型相位匹配，并由锁模和调Q的Nd:YLP激光器产生的放大且三倍频的脉冲序列同步泵浦。腔内普克尔盒用于以1至10赫兹的速率切换出单个0.5兆瓦的脉冲。讨论了该振荡器的设计、构造和性能。将测量的性能与设计预测以及详细的数值模拟进行了比较。
