热效应是限制高能激光输出性能的重要因素之一，液体激光体系在此方面具有特殊的优势。开展了二极管抽运无机液体激光器的流动出光实验，实现了流动状态下较长时间高重复频率的激光脉冲输出。测量了激光光谱、激光脉冲波形和单脉冲激光能量等参数，其中激光中心波长为1052.7 nm，脉宽约为170 μs，最大单脉冲能量约为5 mJ。在抽运频率400 Hz时可连续工作10 min以上。但随着抽运频率上升，激光脉冲能量相应下降。结果表明，二极管抽运的无机液体激光体系在流动状态下能有效地避免热沉积，从而实现较长时间、高重复频率的激光脉冲输出，有望发展成为新型高功率、高光束质量激光体系，值得开展深入的实验研究。

Thermal effect is one of the most important factors to limit the output characteristics of high energy lasers, and the liquid laser has special predominance on heat managements. An experiment on inorganic liquid laser pumped with laser diode at flowing state is carried out, and high repeating frequency laser pulse output is achieved in a long time. The laser spectrum,the laser pulse shape, and the single laser pulse energy are measured. The laser center wavelength is 1052.7 nm, the laser pulse time width is 170 μs, and the maximum single laser pulse energy is about 5 mJ. The liquid laser can continue running more than 10 min under pumping frequency of 400 Hz. The pulse energy will decrease with the pump frequency increasing. The experimental results show that the inorganic liquid laser system pumped by laser diode can avoid heat deposition effectively at flowing state, and achieve high repeating frequency laser pulse output in a long time, which has the potential to develop into newstyle high power and high beam quality laser system, and is worth carring out deeper experimental research.
