摘要: 描述了对高功率LD端面泵浦Nd:YLF激光放大器的研究。放大器的耦合结构采用微透镜对泵浦光进行准直,透镜导管(Lensduct)对其汇聚,耦合效率达72.2%。用该放大器构成的振荡器的斜效率为35.9%。该激光放大器的口径为Φ 10mm,在1053nm处具有2.66的小信号增益。Abstract: The study on high power laser diode arrays end-pumping Nd:YLF laser amplifier is discussed in this paper. The amplifier’s coupling structure ineludes a microlens which collimates the pumping light and a lensduct which focuses it into the laser rod. Its coupling efficiency is up to 72.2%. The slope efficiency of the laser oscillator composed by the amplifier is 35.9%. A small signal gain of 2.66 is obtained at 1053nm.
