Abstract

In this paper, we demonstrate high peak power mid-infrared tunable Raman soliton generation in a large-core diameter short-length fluorotellurite fiber. The pump source uses a tunable Raman soliton generated in a large mode area (LMA) silica fiber with a narrowest pulsewidth of 78 fs, a pulse energy of up to 104 nJ, and a peak power of up to 1.3 MW. Subsequently, a Raman soliton at 3.7 μm was obtained using this Raman soliton pulse as a pump source to further pump a 25 μm core diameter fluorotelluride fiber. The peak power of the Raman soliton in the mid-infrared was tested to be about 0.52 MW, with a pulse energy of 40 nJ and a pulsewidth of about 77 fs. These output parameters validate the great potential of fluorotellurite fibers as a nonlinear frequency-shifting medium for obtaining ultrashort pulses in the mid-infrared region
