Abstract

We report on a diode-pumped master-oscillator/fiber-amplifier (MOFA) system consisting of a passively Q-switched, single-frequency Nd:LSB microchip laser that seeds a dual-stage Yb-doped fiber amplifier. A large-core, single-mode photonic crystal fiber was used for the final amplifier. The MOFA generated 1062nm wavelength, 1-ns long, ~10kHz repetition-rate, diffraction-limited pulses of energy >1mJ, peak power >1MW, average power >10W, and spectral linewidth ~9 GHz.

摘要

我们报道了一种二极管泵浦主振荡器/光纤放大器（MOFA）系统，该系统由一个被动调Q、单频Nd:LSB微芯片激光器作为种子源，泵浦一个两级掺镱光纤放大器。最后一级放大器采用了大芯径单模光子晶体光纤。该MOFA产生波长为1062nm、脉宽1ns、重复频率约10kHz、衍射极限的脉冲，能量>1mJ，峰值功率>1MW，平均功率>10W，光谱线宽约9GHz。
