摘要
通过光学自组装方法制备了碲化铋可饱和吸收器件,并获得了该器件的非线性光学响应特性。将可饱和吸收体引入掺铒光纤激光器中,在抽运功率为170mW时,获得中心波长为1564.94nm,脉冲宽度为2.91μs的激光输出。通过外加连续光对非线性吸收器件进行调制,实现了脉冲持续时间和重复频率可调控的调Q光纤激光输出。
The saturable absorber Bismuth Telluride nanosheets are synthesized via optical self-assembly method,and the nonlinear optical response characteristics are obtained.By introducing the saturable absorber into the Erdoped fiber laser,the Q-switched fiber laser can deliver the pulse laser with pulse duration of 2.91μs,wavelength of 1564.94 nm with the pump power of 170 mW.With the modulation of continuous wave laser on nonlinear absorption devices,the pulse duration and repetition frequency tunable Q-switched fiber laser is realized.
