In the ring cavity laser based on nonlinear polarization rotation effect,the output of double pulse was obtained by adding a high nonlinearity fiber of 5 m.In order to test the composition of double pulse,the outputs of double pulse at a central wavelength 1546 nm and 1558 nm were respectively obtained through placing the tunable filter at the output of the laser.The experimental results prove that the double-pulse is made of two single pulses with different wavelengths.
