摘　　要：将 F-P LD与环形光纤激光器结合起来 ,以 LD作为调制器 ,与 M-Z干涉型调制器相比 ,大大减小环形腔内的损耗 ,在较低的增益下仍可得到稳定的锁模脉冲 .并通过改变 LD工作温度实现激光波长连续调谐 ,调谐范围1 nm.所得脉冲重复速率约为 2 GHz,脉冲宽度平均 5 0High stable single wavelength pulse train was generated by combining F-P semiconductor laser diode and fiber ring laser. In this experiment, F-P LD acted as a modulator and a tunable filter. Compared with M-Z interferometer modulator, the stable mode-locked pulse was obtained in the condition of lower gain for lower cavity loss. A continuous wavelength tuning range of 1 nm was achieved by changing the LD temperature. The frequency pulse with pulse-width 50 ps was 2 GHz.
