摘　　要：在基于非线性偏振旋转效应的环形腔激光器中,通过添加一段长为5 m的高非线性光纤,得到了双脉冲的输出,为了检验双脉冲的组成,在激光器的输出放置一个可调滤波器,在中心波长1546 nm和1558 nm处分别得到了双脉冲的输出,证明双脉冲是由波长不同的两个单脉冲叠加而成的。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.
