摘要

通过掺红镨激光器与掺四倍频掺钕激光器的混频，研制出了脉冲在5 ~ 15khz范围内的194nm激光器。利用电光调q腔倾倒产生的红色激光具有kW的峰值功率和恒定的短脉冲持续时间。在7 kHz时，在194 nm处实现了34.7 mW的最大平均输出功率。脉冲持续时间保持在5.1 ns，与重复频率无关。在5 kHz时获得最大脉冲能量5.7 μJ，峰值功率达1.12 kW。

Generation of 194 nm Deep-UV pulses using a Cavity-Dumped 721 nm Pr:YLF laser with Tunable repetition rates

A compact 194 nm laser with a few-ns pulse from 5 to 15 kHz is developed by frequency mixing a red Pr-doped laser with a fourth-harmonic Nd-doped laser. The red laser was generated by electro-optic Q-switched cavity dumping, which has kW peak power and constant short pulse duration. The maximum average output power of 34.7 mW at 194 nm was realized at 7 kHz. The pulse duration was maintained at 5.1 ns, which is independent of the repetition rate. The maximum pulse energy of 5.7 μJ was obtained at 5 kHz, and the corresponding peak power was up to 1.12 kW.
