Watt-level and spectrally flat mid-infrared supercontinuum in fluoroindate fibers
Fig. 1. (a) Experimental setup of the MIR SC fiber source. PA, pre-amplifier; CMS, cladding mode stripper; DCF, double-clad fiber; SCF, single-clad fiber; ISO, 2 μm optical isolator (Thorlabs, IO-K-2000); L, fiber length. (b) Spectral distribution of the Er/Yb amplifier (blue line), output of the fiber isolator (green line), and the Tm amplifier (black and red lines).
Fig. 2. (a) Spectral distribution of the Tm amplifier (black line) injected into fluoride fibers. The SCs from the 20-m ZBLAN and 20-m
Fig. 3. (a) Spectral distribution at the output of the 20-m long
Fig. 4. (a) 10-dB spectral bandwidth as a function of the SC output power. (b) SC output power as a function of the Tm amplifier output power. (c) Spectral distribution at the output of fluoride fibers. The laser power from the Tm amplifier was fixed to 2.3 W for the three cases presented, and the SC output powers are indicated in parenthesis.
