A stable output can be obtained in a disordered system by injection locked. In this paper, a wavelength injection locked coherent random fiber laser based on the random phase shift fiber Bragg grating is proposed and experimentally proved. A stable single wavelength can be obtained by injecting a wavelength tunable laser into the cavity of random fiber laser with unstable output. The central wavelength drift is less than 0.01 nm and the peak power fluctuation is less than 0.1 dBm within one hour. The injected light power threshold of wavelength locked increases inversely exponentially with the increase of pump power. Different laser modes with stable central wavelength and peak power can be selected by changing the wavelength of injected light within the 0.8 nm reflection bandwidth of the random phase shift fiber Bragg grating. The output power increases linearly with increasing pump power, and the slope efficiency is about 4%. [ABSTRACT FROM AUTHOR] |
