The emission wavelength of semiconductor laser varies with the change of working current and temperature,which affects the effective linewidth and wavelength stability of the output laser,and cannot meet the requirements of the gain medium in the solid-state laser for the pump source wavelength and linewidth.In this paper,a self-developed reflective holographic volume Bragg grating (VBG) of 878 nm with a diffraction efficiency of 9.9% is designed.By using the VBG as a reflective cavity mirror,the laser emission wavelength can be locked around the designed 878 nm and an output linewidth is only 0.3 nm.The wavelength-current drift coefficient is 0.015 nm/A and the temperature drift coefficient is 0.007 5 nm/°C.An all-solid-state laser is constructed by using a wavelength locking semiconductor laser as the pump source.The self-developed 1 064 nm VBG with a diffraction efficiency of 98.71% and 94.32% is used as the front and rear cavity mirrors, respectively.A Nd∶YVO4 crystal with a doping concentration of 0.3% is used as the gain medium.After the spatial optical path tuning,a continuous and stable laser output with a central wavelength of 1 064.2 nm and a line width of 0.29 nm are obtained.
