摘要	The 780.0 nm narrow linewidth and high power diode laser is of great significance for the development of Rb alkali metal vapor laser. In order to obtain good pumping effect, the absorption spectra of the pump spectrum and the alkali metal vapor must be strictly matched, the output line width of the diode laser must be narrowed, and the central wavelength must be stabilized. External cavity feedback of reflective volume Bragg grating(RVBG) is one of the main schemes to realize narrow spectrum light source at present. The structure of fast axis collimating mirror, beam convertor, slow axis collimating mirror, reflection type body Bragg grating(FAC-BTS-SAC-RVBG) is proposed. The laser divergence angle of incident to RVBG is compressed to improve the effective response rate of RVBG. Compared with the conventional "FAC +SAC+RVBG" structure, the spectral locking effect is improved. Based on the FAC-BTS-SAC-RVBG structure, a narrow linewidth laser at 780 nm was developed, with a continuous power of 50 W. By controlling RVBG temperature, the central wavelength could be stabilized at 780.00 nm. Using single mode optical fiber probe, spectral width is 0.064 nm(FWHM), temperature drift coefficient is 0.001 2 nm/, current drift coefficient is 0.001 3 nm/A. The structure can be used for Rb alkali metal vapor laser pump. 2019, Science Press. All right reserved.
