In high power end-pumped solid state laser, the conventional Nd∶YAG crystal can be influenced by LD wavelength shift induced by temperature shift due to its narrow absorption bandwidth, which will lead to fluctuating of output power. In order to reduce the sensitivity of laser which is influenced by LD temperature, a combination crystals scheme between Nd∶YAG and Nd∶YVO4 is proposed. The Nd∶YAG with good thermophysical parameters is placed at the front end of LD to absorb most pumped energy, and Nd∶YVO4 with broad absorption spectrum at the rear of Nd∶YAG to absorb the rest pumped energy. The absorption efficiency and output power of the laser can be kept stable through the above complementary absorption during LD wavelength shift, and more tolerant to LD temperature variations. Experimental results show that the absorption efficiency of pumped energy can be improved to 90% by using the combination crystals at LD power 97.5 W in the range of LD work temperature 22-32 ℃. And the output power fluctuation is less than 8%, which reduces the sensibility to the LD temperature.
