In this work, a high-power all-fiber mid-infrared (MIR) supercontinuum (SC) laser source was generated in a short piece of centimeter level germania-doped fiber (GDF). The MIR SC generation in GDF was pumped by a 2 μm chirped pulse amplification (CPA) system.

N/A. Abstract. Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort laser pulses and optical fibers. These light sources have high brightness and are spatially coherent. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated.

A supercontinuum (SC) source is typically a pulsed laser (in the nanosecond, picosecond or femtosecond regime) that is converted into an optical signal having a very broad spectrum, as illustrated in Fig. 1. As compared to standard illuminating broadband light sources like a lamp, a LED, or even the sun, supercontinuum sources have one of the ...

The interaction of a high peak power pump laser with the material constituting the fiber allows to generate a multitude of wavelengths, i.e., a supercontinuum. Our supercontinuum lasers cover wavelengths from UV (320 nm) to mid-IR (4500 nm) , with different modes of operation (from pulse-on-demand (10 Hz) to quasi-CW (MHz)) and different pulse ...

In this letter, we demonstrate a 25.8 W all-fiber mid-infrared supercontinuum (SC) light source based on fluorotellurite fibers. All-solid fluorotellurite fibers are fabricated by using a rod-in-tube method.

We report on far-infrared filament-induced supercontinuum obtained with three chalcogenide glasses. The introduction of more polarizable elements (Se instead of S and Te instead of S and Se) into the glasses increases their non-linearity and transmission window and also shifts gradually corresponding zero-dispersion wavelength in the infrared region.
