Abstract:

In this paper, we demonstrate high-power mid-infrared (MIR) tunable Raman soliton generation in a large core diameter fluorotellurite fiber. Using a 1960 nm high-power femtosecond fiber laser as the pump source, a high-power 2.15 μm Raman soliton with a pulse width of less than 150 fs is first generated in a 32 μm core diameter passive fiber. Subsequently, the large core diameter silica fiber was used to cascade-pump a 1.8 m fluorotellurite fiber with 34 μm core diameter to obtain a tunable MIR Raman soliton in the range of 2.1-3.5 μm. The farthest Raman soliton with a central wavelength of 3450-nm was tested to have an output power of about 0.6 W and a pulse width of about 120 fs. To the best of our knowledge, this is the widest range of Raman soliton obtained in tellurite fibers to date.  © 2024 IEEE.
