A laser diode array (LDA) end-pumped continuous-wave single-frequency Innoslab amplifier has been demonstrated. The Gaussian ray bundle method was used to model the light propagation in the Innoslab amplifier for the first time to the best of our knowledge. With discrete reflectors, the maximum output of 60 W with a linewidth of 44 MHz was achieved under the pump power of 245 W, corresponding to the optical-optical efficiency of 24.5%. The beam quality factor M at the output power of 51 W in the horizontal and vertical direction was measured to be 1.4 and 1.3, respectively. The long-term power instability in 2 h was less than 0.25%.
已展示了一种激光二极管阵列（LDA）端面泵浦的连续波单频Innoslab放大器。据我们所知，首次使用高斯光线束方法对Innoslab放大器中的光传播进行建模。通过分立反射镜，在245W泵浦功率下实现了60W的最大输出，线宽为44MHz，对应光光效率为24.5%。在51W输出功率下，水平和垂直方向的光束质量因子M分别测得为1.4和1.3。2小时内的长期功率不稳定性小于0.25%。
