We report on high-power laser-diode (LD) end-pumped Tm:YLF innoslab lasers with different doping concentrations of 2, 2.5, and 3 at.% with a single-end 792 nm LD stack. After series of experiments, we conclude that 3 at.% Tm:YLF lasers can produce a maximum output power of 84.7 W; this value is higher than that of the lasers with two other doping concentrations at the same incident pump power equal to 348 W. The corresponding optical-to-optical efficiency and the slope efficiency with respect to the absorbed pump power are 27.9% and 52.7%, respectively. The emission wavelength is 1909.6 nm with a FWHM of 1.3 nm. The M₂ factor of the output power at 55 W is 498 along the x axis and 1.8 along the y axis. The shape of the output light is a rectangular spot, which is appropriate for pumping Ho-doped slab lasers.

我们报告了高功率激光二极管（LD）端泵浦的Tm：YLF Inslab激光器，其掺杂浓度分别为2、2.5和3 at。％，具有单端792 nm LD堆栈。经过一系列实验，我们得出结论，3 at。％Tm：YLF激光器可以产生84.7 W的最大输出功率；该值高于在相同入射泵浦功率下等于348 W的其他两种掺杂浓度的激光器的光通量。相对于吸收的泵浦功率，相应的光学效率和斜率效率分别为27.9％和52.7％。 ， 分别。发射波长为1909.6 nm，FWHM为1.3 nm。55 W时输出功率的M ₂系数沿x轴为498，沿y为1.8轴。输出光的形状是一个矩形点，适合于泵浦掺Ho的平板激光器。
