摘　　要：A 2-μm composite Tm：YAG laser pumped with a narrow-band laser diode was presented. The temperature distribution and thermal lens in the Tm：YAG were numerically simulated by a finite element method and the results were used to design the special cavity, in order to achieve a high efficiency and stable output. With a 25-W incident pump power, we obtained a maximum output power of 11 W at 2018.5 nm, corresponding to a slope efficiency of 51.3% and an optical-to-optical efficiency of 44.5%, respectively. The beam quality was measured to be M_x^2= 1.8 and M_y^2= 1.6.A 2-μm composite Tm：YAG laser pumped with a narrow-band laser diode was presented.
