报道了一种工作在2.8微米波长的30W级连续波(CW)氟化物光纤基主振荡功率放大器(MOPA)。为了克服ZBLAN光纤耐久性差的问题，该系统采用了多种新技术，将氟化物玻璃与基于ZBLAN光纤的侧面泵浦组合器相结合。最大连续输出功率为33W，并在23W输出下稳定工作。我们认为，这种光纤MOPA系统将为下一代高功率中红外激光器开辟先进的氟化物光纤技术。(C)2019年美国光学学会
A fluoride-fiber-based master oscillator power amplifier (MOPA) for 30-W class continuous-wave (cw) operation at 2.8-mu m wavelength has been demonstrated. To overcome the low durability of ZBLAN fibers, various novel technologies for using fluoride glass with a ZBLAN-fiber-based side-pump combiner have been adopted in the system. A maximum cw output power of 33 W and stable operation under 23-W output have been demonstrated. We suggest that such fiber MOPA systems will open up advanced fluoride fiber technology for next-generation high-power mid-IR lasers. (C) 2019 Optical Society of America
