Abstract

Mid-infrared supercontinuum has been widely used in biomedicine, spectroscopy and other fields. With the development of fluoride fiber, the output power of mid-infrared supercontinuum has gradually increased. In this paper, the supercontinuum generation system of InF3 fiber pumped by a supercontinuum laser with a spectral range of 1.9-2.6 μm is presented. By optimizing the cooling device, the supercontinuum laser with an output power of 26.2 W and an output spectral range of 1.95-4.5 μm is realized. To our knowledge, this is the first report of mid-infrared supercontinuum output with an average power exceeding 20 W in InF₃ fiber.
