摘要
报道了全光纤结构主动锁模掺铥脉冲激光器，中心波长为1950nm。利用电光相位调制器对光纤激光器进行腔内相位调制，获得了重复频率为11．884MHz的主动锁模脉冲输出，脉宽为816ps。改变泵浦功率、调制信号的频率和幅度，获得了重复频率为4～18kHz的弛豫振荡调制稳定脉冲输出。锁模和弛豫振荡调制获得的输出脉冲能量波动低于7％。
An all-fiber Tm-doped pulse laser with active mode-locking is demonstrated, the center wavelength is 1.95μm. The phase in the laser cavity was modulated by an electronic optical phase modulator, and an actively mode-locked pulse output with a repetition rate of 11. 884 MHz was obtained, the pulse duration was 816 ps. Relaxation oscillation modulated stable pulse train with a repetition rate of 4-18 kHz was realized by adjusting the pump power, the frequency and amplitude of modulating sig- nal. All the energy fluctuations of the stable pulse trains were less than 7 %.
