摘要	It was proposed and demonstrated that a high beam quality self-pulse could be achieved by off-axis feedback for 1.95-mu m GaSb-based broad-area laser. The comparative studies of on-axis feedback and off-axis feedback were conducted in an experiment. A highly reflecting (HR) mirror with sharp edge was used in the off-axis feedback system and the overlapping size was changed by moving the HR mirror. At the direct current of 1.8 A, 45-cm external cavity length, and 36% strength of feedback, the off-axis feedback with the overlapping size of 1.2 mm could accomplish the regular periodic pulse with the frequency of 153 MHz. The beam quality M-2 was 12.75 in slow axis and improved nearly doubled compared with that in the on-axis feedback system. (C) 2020 Society of Photo-Optical Instrumentation Engineers (SPIE)
