All-fiber actively mode-locked Tm-doped pulse laser at 2 μm
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1950 nm。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11.884 MHz的主动锁模脉冲输出,脉宽为816 ps。改变泵浦功率、调制信号的频率和幅度,获得了重复频率为4~18 kHz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%。
Abstract
An all-fiber Tm-doped pulse laser with active mode-locking is demonstrated, the center wavelength is 1.95 μm. 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 signal. All the energy fluctuations of the stable pulse trains were less than 7%.
