摘要
报道了一台适用于分布式光纤传感的全光纤激光器。激光器基于主振荡功率放大(MOPA)技术，种子光源为半导体激光器，放大器为掺铒光纤放大器。实现了重复频率和脉冲宽度分别独立可调的激光输出，中心波长为1550 nm，光谱的3 dB带宽小于0.2 nm，获得的最高峰值功率为1.1 kW，输出的激光脉冲中放大自发辐射(ASE)功率分数的最大值低于10%。
Abstract
An all fiber laser which is suitable for distributed optical fiber sensor is reported. The laser is based on the technique of master-oscillator-power-amplifier (MOPA), whose seed laser is a laser diode and amplifier is Er3+ doped fiber amplifier. The laser operates in wavelength of 1550 nm with the tunable repetition rate and the pulsewdith, and the 3 dB width is less than 0.2 nm. The maximum peak power 1.1 kW of laser pulse is obtained, and the power of amplified spontaneous emission (ASE) in the output pulse is less than 10% in all condition.
