Abstract

The passively mode-locked of nonlinear amplifying loop mirror(NALM) configuration is used to study the influence of mode-locked pulse induced by the nonlinear effect of optical fiber.After analyzing the transmission characteristic theory of nonlinear amplifying loop mirror,experiments were executed for a passively mode-locked erbium-doped fiber laser.It was found that the steady mode-locked pulse phenomenon with repeat frequency of 280.2MHz,center wavelength of 1556.235nm and line width of 0.4nm.The study is helpful for thorough understanding the passively mode-locked phenomenon and follow-up research.
