Abstract

We report, as far as we know for the first time, on a pulsed 2.7 µm Er:ZBLAN fiber laser -switched by an electro-optic modulator. The -switched operation was achieved with a repetition rate range of 100 Hz-50 kHz. Pulse energy of 205.7 µJ and pulse width down to 13.1 ns, yielding a peak power of 15.7 kW, were obtained at a repetition rate of 100 Hz. The linewidth of the output spectrum was as narrow as 0.4 nm. The pulse width and the pulse peak power, to the best of our knowledge, are currently the shortest and the highest in the 3-µm-band -switched fiber lasers, respectively.

摘要

据我们所知，我们首次报道了一种由电光调制器切换的脉冲2.7微米掺铒氟化物玻璃光纤激光器。切换操作在100 Hz至50 kHz的重复频率范围内实现。在100 Hz的重复频率下，获得了205.7 μJ的脉冲能量和低至13.1 ns的脉冲宽度，产生了15.7 kW的峰值功率。输出光谱的线宽窄至0.4 nm。据我们所知，在3微米波段的切换光纤激光器中，目前该脉冲宽度最短，脉冲峰值功率最高。
