The laser performance of two a-cut Tm:YLF slab crystals with c-axis along the x-direction and y-direction is compared. These two lasers are compared under identical pump conditions in a continuous wave regime. A maximum output power of 135 W at 1908 nm Tm:YLF laser with two slab crystals is obtained, corresponding to an optical-to-optical efficiency of 43.3% and a slope efficiency of 50.6% with the respect to the absorbed pump power of 312 W. At the output power of 110 W, the M ² factors in the x-direction and y-direction are 293 and 1.74, respectively. The shape of the output light is a rectangular spot. The polarization of the output light is σ-polarized.
