AI Article Synopsis
- The study presents the creation of high-power tunable Raman solitons between 3.3-3.8 µm using fluorotellurite fiber, a material known for its high nonlinearity.
- The pump source used for this process is a 2.15-2.3 µm Raman soliton that achieved a peak power of 3.8 MW, marking a record in silica fibers.
- Despite the high power, the resulting Raman soliton maintained a very narrow pulse width of 70.4 femtoseconds and an output power of 1.36 W, representing the peak performance in mid-infrared fibers.
Article Abstract
We report the generation of MW-class tunable Raman solitons of 3.3-3.8 µm in a fluorotellurite fiber. The pump source of the mid-infrared fiber is a 2.15-2.3 µm Raman soliton source which has the highest peak-power Raman soliton (3.8 MW) ever achieved in a silica fiber. Fluorotellurite fiber is characterized by its short length and high nonlinearity, preventing the Raman soliton pulse broadening that occurs with fiber dispersion. The Raman soliton shifted to 3.8 µm while still maintaining an ultra-narrow pulse width of 70.4 fs with 1.36 W output power and 1.17 MW peak power. To the best of our knowledge, this is the highest peak-power Raman soliton obtained in a mid-infrared fiber.
