通过数值仿真和实验研究了基于非线性偏振旋转技术的被动锁模光纤激光器中孤子的形成。结果表明，Maxwell-Bloch方程描述的光纤激光器，由于脉冲峰值箝制效应，激光器中可以形成稳定的孤子。当形成的孤子强度被箝制在较大值时，频谱展宽。继续增大被箝制的强度时，孤子的强度不再增大，而是形成新的孤子。

The formation of soliton in the passively mode-locked fiber laser based on nonlinear polarization ro?tation technology is simulated numerically and investigated experimentally. The results show that due to the cavity pulse peak clamping effect, stable solitary waves can still be obtained in the laser which is described by the Max?well-Bloch Equation. The higher density of the clamped soliton is, the wider frequency is. With the clamped density is increased, the soliton density is not increased, and the new soliton is formed.
