摘　　要：开展了二极管抽运流动无机液体激光体系的激光实验研究,获得了长时间稳定的准连续激光输出,抽运频率300 Hz时的平均输出功率超过10 W,光光转换效率约为6%。实验中研究了抽运电流、抽运频率、输出耦合率和磁力泵转速对平均输出功率的影响,并进行了初步的理论分析,为进一步开展无机液体流动激光实验研究积累了经验。同时,很好地解决了无机激光液体的长时间保存技术问题,有效地避免了激光液体光学性能的退化。实验结果表明,二极管抽运的无机液体体系在流动时能有效地避免热沉积,可以获得长时间稳定的准连续激光输出。Lasing experiment of inorganic liquid system pumped bilaterally with laser diode array under flowing state is carried out, and the smooth quasi continuous-wave laser output for long time is achieved. The average laser output power is higher than 10 W when the pumping frequency is 300 Hz, and the optical to optical efficiency is about 6 %. The influence of pumping current, pumping frequency, output coupling ration and the rotate speed of magnetic pump on the laser average output power is researched, and the elementary academic analysis is carried out. The experience for the further lasing experimental research of the inorganic liquid laser system under flowing state is accumulated. At the same time, the preservation technology problem of inorganic laser liquid for long time is solved and the optical performance degradation for the inorganic laser liquid is avoided effectively. The experimental results show that the inorganic liquid laser system pumped by laser diode array can avoid heat deposition effectively at flowing state and obtain the smooth quasi continuous-wave laser output in long time.
