Picosecond Erbium-Doped Fiber Laser based on Gain-Switched Laser Diode
摘要
报道了基于半导体增益开关技术的皮秒脉冲掺铒激光器，该激光器可输出脉冲宽度为80 ps的光脉冲，具有重复频率可调的特点（100 kHz~20 MHz）。在重复频率为20 MHz时，经过主功率振荡放大器（MOPA）后，激光器输出的平均功率为9.3 W，相应的脉冲峰值功率为5.8 kW；最高功率输出时，脉冲信噪比达40 dB。
Abstract
A picosecond erbium-doped fiber laser based on gain-switched laser diode is demonstrated. The gain-switched laser diode seed can produce 80 ps pulses with tunable repetition rates from 100 kHz to 20 MHz. After master-oscillator power-amplifier (MOPA), this fiber laser yields 9.3 W average power at 20 MHz repetition rate, corresponding to 5.8 kW peak power.
