高峰值功率中红外2.8 μm脉冲光纤激光器
High Peak Power Mid-infrared 2.8 μm Pulsed Fiber Laser
摘要
采用中心波长为975 nm半导体激光器泵浦高掺铒氟化物双包层光纤Er∶ZBLAN, 并在谐振腔内插入主动调Q元件, 获得了工作频率为1~10 kHz的2.8 μm激光主动调Q脉冲输出.在工作频率为10 kHz条件下, 获得了最大单脉冲能量为134.5 μJ、脉宽为127.3 ns、峰值功率为1.1 kW的脉冲输出.
Abstract
A high peak power actively Q-switched mid-infrared fiber laser at 2.8 μm was demonstrated with a repetition rate of 1~10 kHz by employing a 975 nm laser-diode to pump a piece of heavily Er3+-doped ZBLAN double-clad fiber and a mechanical chopper into the cavity as the Q-switch. Stable Q-switched laser pulse with a maximum pulse energy of 134.5 μJ, pulse duration of 127.3 ns and peak power of 1.1 kW was obtained at a repetition rate of 10 kHz under a proper pump power.
