Abstract

According to the geometric relationship of the thermal stable cavity of the intracavity pumped dual wavelength narrow line-width laser structure and fundamental mode, the temperature distribution inside two gain mediums were analyzed, the temperature on the end surface of Nd:GdVO₄ laser gain medium is 295.51K, it means that the heat source temperature of the thermal temperature distribution of Nd:YVO₄ laser gain medium in the cavity. The thermal temperature distribution of Nd:YVO4 laser gain medium in the cavity is obtained, the result shows that exist a relatively serious thermal effect in the quasi-three-level laser gain medium Nd:GdVO₄, which restrict the improvement of intracavity pumped dual wavelength narrow line-width laser performance.
