We present an all-fiber Raman laser based on a mid-infrared compatible and highly nonlinear As38Se62 core/As38S62 cladding chalcogenide microwire. The laser operates at a wavelength of 2.025 μm with a low threshold peak power of 4.6 W. Pulse width can be compressed to the femtosecond scale.
Abstract-We investigate the fluorescence spectra of a ZBLAN fiber as a function of the laser pumping source wavelength, 790 nm and 980 nm, with an aim to optimize the fluorescence at 2.7 μm. A theoretical model based on the energy band diagrams of erbium has been built to support the results.
Cascaded stimulated Raman scattering emission is reported in high-Q As2S3 microspheres for the first time. Stimulated Raman scattering emission is observed up to the 5th order with a pump power of 500 μW at 1550 nm.
We present a chalcogenide microwire device that acts as a compact (∼11 cm length, ∼1 µm diameter) and power efficient (sub-Watt threshold peak power, >2% slope efficiency) Raman-parametric laser, wavelength converter and ultra-broadband supercontinuum generator/amplifier.
Compact, power efficient, and fiber-compatible lasers, wavelength converters, and amplifiers are vital devices for the future of fiber-optic systems and networks. Nonlinear optical effects, like Raman scattering and parametric four-wave mixing, offer a way to realize such devices. Here, we use a single chalcogenide microwire to realize a device that provides the functions of a Stokes Raman-parametric...
We present telecommunications band, chalcogenide microwires based Raman lasers in two cavity configurations. One cavity is a fiber loop type (chalcogenide microwire-plus-silica fiber), while the other cavity is an all-chalcogenide Fabry-Perot type.
We study continuous-wave laser operation of a Cr:ZnSe:glass composite waveguide. Results show the influence of propagation losses on the power conversion efficiency, pumping range and the wavelength tunability of the laser.
