摘要
报道了一台实用化的基于主振荡-功率放大(MOPA)方式工作的全光纤高重复频率脉冲激光器。以基于高速MOSFET驱动电源的调制激光二极管(LD)作为种子激光器, 采用两级串联的单模双包层光纤作为预放, 利用双包层光纤为主放。该器件可以得到重复频率高达600 kHz的窄脉冲输出。在重复频率125 kHz时, 得到脉宽10 ns, 平均功率2.4 W的激光输出。研制的激光器具有较好的稳健性, 将应用到空基的三维成像激光雷达中。
Abstract
A practical pulsed fiber laser based on master-oscillator power amplifier (MOPA) architecture is reported. A laser diode (LD) driver based on high-speed MOFSET is used as seed laser. The single mode double-cladding fiber is used in the two stages as preamplifier, and the double-cladding fiber is used in the booster. The laser can generate narrow pulse width output at repetition frequency of up to 600 kHz. At repetition frequency of 125 kHz, amplified laser with average power of 2.4 W and pulse width of 10 ns is generated. This robust pulsed laser is a good candidate for space-based 3D imaging lidar.
