双包层掺Yb3+光纤环形脉冲激光形成研究

Numerical simulation of the dynamics characteristics of Yb 3+ doped fiber ring laser using the polarization sensitive ISO is reported. The result show that using the additive pulse mode locking based on nonlinear polarization evolution ,the Yb 3+ doped ring laser without the dispersion compensation can operate different region by adjusting the orientation of polarize controller. In the experiment, the 976 nm semiconductor laser is used as the pumped power, by adjusting the position of the PC, the Yb 3+ doped fiber laser can oscillate at the state of the CW and self pulsation, the period of the self pulsing is determined by the cavity length of fiber laser.
