摘要

报道了工作波长为2.94µm的掺Dy3+增益开关ZBLAN光纤激光器的实际实现。激光由一个1.1µm调q镱(III)光纤激光器泵浦，该激光器是内部构建的。ZBLAN光纤激光器产生稳定的脉冲序列，重复频率从25到100千赫。在重复频率为50 kHz时，脉冲宽度为183 ns，能量和峰值功率分别为0.72µJ和4 W。

Pulsed fluoride glass fiber laser with near 3 µm operating wavelength

Practical realization of gain-switched Dy3+-doped ZBLAN fiber laser operating at 2.94 µm is reported. The laser is pumped by a 1.1 µm Q-switched ytterbium (III) fiber laser, which was constructed in-house. The ZBLAN fiber laser generates a stable pulse train with repetition rates spanning the range from 25 to 100 kHz. At the repetition rate of 50 kHz, the pulse width is 183 ns while energy and peak power are 0.72 µJ and 4 W, respectively.
