Diode-end-pumped continuous-wave （CW） Tm：YAP and Tm：YLF slab lasers are demonstrated. The a- cut Tm：YAP and Tm：YLF slabs with doping concentrations of 4 at.-% and 3.5 at.-%, respectively, are pumped by fast-axis collimated laser diodes at room temperature. The maximum CW output powers of 72 and 50.2 W are obtained from Tm：YAP and Tm：YLF, respectively, while the pump power is 220 W, corresponding to the slope efflciencies of 37.9% and 26.6%, respectively.
