【Abstract】 A stable single-frequency and linear polarization fiber ring laser with linewidth less than 0.75KHz is demonstrated in which a fiber polarizer and a self-written fiber grating induced by saturation absorption inner an unpumped Er3+ doped fiber at the standing-wave section are applied. Its output is characterized by obvious optical bistability.更多还原
