【Abstract】 A Fiber Bragg Grating(FBG) with weak feedback is utilized to keep an uncooled 980 nm pump laser operating in a coherence-collapse state,greatly improving the stability of its wavelength and output power. The effects of the main FBG parameters on the output power and spectrum of the laser in the experiment are analyzed,which shows that the optimized FBG parameters can stabilize the laser operating over a range of 0~70 ℃.更多还原
