Abstract

Abstract

The paper demonstrated that by using the nonlinear polarization rotation as the mode-locking mechanism, the laser could operate stably in either CW fundamental wave mode-locked or high-order harmonically mode-locked regimes by changing the pump power and adjusting the polarization controller. Under the pump power of 10 mW, fundamental wave mode-locked pulses with repetition rate of 15.89 MHz, output spectrum width of 9.9 nm, central wavelength of 1.557 nm was obtained. Under a different pump power of 75 mW, we obtained second harmonically mode-locked pulses with repetition rate of 31.79 MHz and third harmonically mode-locked pulses with repetition rate of 46.68 MHz. The paper also presented some preliminary theoretical analyses.
