作者姚金妹,张斌,殷科,侯静（2019）在《The 2-μm to 6-μm mid-infrared supercontinuum generation in cascaded ZBLAN and As2Se3 step-index fibers》一文中研究指出：Fiber-based mid-infrared（MIR） supercontinuum（SC） sources benefit from their spectral brightness and spatial coherence that are needed for many applications, such as spectroscopy and metrology. In this paper, an SC spanning from 2 μm to 6 μm is demonstrated in cascaded ZrF4–BaF2–LaF3–AlF3–NaF（ZBLAN） and As2Se3 step-index fibers. The pump source is a ZBLAN fiber-based MIR SC laser with abundant high-peak-power soliton pulses between 3000 nm and 4200 nm. By concatenating the ZBLAN fiber and the As2Se3 fiber, efficient cascading red-shifts are obtained in the normal dispersion region of the As2Se3 fiber. The spectral behavior of cascaded SC generation shows that the long-wavelength proportion of MIR SC generated in the ZBLAN fiber plays a critical role for further spectral extension in the As2Se3fiber.
Abstract
Fiber-based mid-infrared（MIR） supercontinuum（SC） sources benefit from their spectral brightness and spatial coherence that are needed for many applications, such as spectroscopy and metrology. In this paper, an SC spanning from 2 μm to 6 μm is demonstrated in cascaded ZrF4–BaF2–LaF3–AlF3–NaF（ZBLAN） and As2Se3 step-index fibers. The pump source is a ZBLAN fiber-based MIR SC laser with abundant high-peak-power soliton pulses between 3000 nm and 4200 nm. By concatenating the ZBLAN fiber and the As2Se3 fiber, efficient cascading red-shifts are obtained in the normal dispersion region of the As2Se3 fiber. The spectral behavior of cascaded SC generation shows that the long-wavelength proportion of MIR SC generated in the ZBLAN fiber plays a critical role for further spectral extension in the As2Se3fiber.
