摘要:
利用非线性放大环形镜被动锁模方法对锁模光纤激光器进行实验研究,引入色散管理方法,实现了“8”字形掺铒光纤激光器的自启动被动锁模,在1550 nm波段上得到了光谱宽度16 nm、脉宽为1.77×10-13 s的超短脉冲输出.泵浦功率在300 mW时,激光器实现了重复频率为19.7 MHz,平均输出功率12 mW的锁模脉冲输出.整个激光腔为全光纤结构,而且操作简单,锁模输出状态下的激光器可以在光学平台上稳定运行数小时.
Abstract:
The experimental study of Erbium doped fiber lasers using the nonlinear amplifying loop mirror for mode-locked operating is reported. we optimize dispersion management in the cavity. The fiber figure-8 erbium doped laser can realize self-starting passively mode-locked and directly produce 1.77?10?13 s ultrashort pulses output in 1 550 nm wavelengths. The average output power was 12 mW under a 300 mW pump power with a repetition rate of 19.7 MHz. The laser is operated simply because of all-fiber construction in the cavity. It can steady work hours in optical platform under the mode-locking condition.
