Supercontinuum generation spanning over three octaves from UV to 385 μm in a fluoride fiber

Abstract

We report what we believe to be the first demonstration of supercontinuum generation spanning over three octaves from UV (at least approximately 350 nm) to 3.85 microm in a 2.5-cm-long fluoride fiber pumped by a 1450 nm femtosecond laser. The spectral broadening in the fluoride fiber is caused primarily by self-phase modulation. Its performance is also compared with that of a 2.5-cm-long silica fiber pumped by the same laser.

High-Power ZBLAN Glass Fiber Lasers: Review and Prospect

“…The two problems may be solved by pumping ZBLAN fiber with 1 μm laser. Recently, when a 2.5-cm-long fluoride fiber was pumped by a 1450 nm femtosecond laser, supercontinuum from 0.35 μm to 3.85 μm was generated [188]. However, all these supercontina mentioned above are temporally incoherent.…”

Thulium pumped mid-infrared 09–9μm supercontinuum generation in concatenated fluoride and chalcogenide glass fibers

“…Supercontinuum sources combine all features of a broadband and spatially coherent source having a high intensity [7]. Mid-IR SC laser sources are currently based primarily on ZBLAN fibers covering the 1-4.75μm spectral range [8][9][10][11][12] and tellurite fibers covering the 1-5μm range [13,14]. Mid-IR SC sources have already been successfully applied in FTIR spectroscopy [15] and in hyperspectral imaging [16].…”

Strong infrared spectral broadening in low-loss As-S chalcogenide suspended core microstructured optical fibers

“…The latter parameter is a key tool to obtain an efficient light conversion and to reach accordable fibered broadband sources in the mid infrared. Much effort has been recently devoted to obtain MOF from various glasses [21][22][23]. Nevertheless, an efficient conversion up to 5 µm to cover entirely the 3-5 µm window is still a target to reach.…”
