We have experimentally investigated high-energy rectangular pulses delivering from an erbium-doped fiber laser operating in ultra-large net-negative-dispersion regime. The laser oscillator emits rectangular pulses with approximately Gaussian spectral profiles, adjustable nanoseconds durations, and multi-ten nanojoule energies. The outputted pulses can be further amplified to over 2 μJ without distortion by a two-stage erbium-doped fiber amplifier. Thus, rectangular pulses with controllable durations and energies can be achieved from the compact all-fiber fiber laser system.
我们通过实验研究了在超大净负色散 regime 下运行的掺铒光纤激光器发出的高能矩形脉冲。该激光振荡器发出具有近似高斯光谱轮廓、可调纳秒持续时间和数十纳焦能量的矩形脉冲。输出的脉冲可以通过两级掺铒光纤放大器进一步放大到超过 2 μJ 而不失真。因此,可从紧凑的全光纤激光系统获得具有可控持续时间和能量的矩形脉冲。
