“…reported that a supercontinuum with an output power of 3.96 W was achieved in a GRIN MMF with 62.5 µm core diameter using picosecond pulses at MHz repetition rate [13]. There are also some reports on the generation of supercontinuum in GRIN fibers [14,15]. However, current studies on the generation of supercontinuum spectra based on GRIN fibers were all performed at lower average powers (below 5 W).…”

An all-fiber supercontinuum source based on graded-index multimode fibers is reported. The supercontinuum source is based on a homemade mode-locked oscillator and a three-stage picosecond amplifier, which obtained the supercontinuum by a graded-index multimode fiber. The laser output with a spectral range of 480–2440 nm, an average power of 25 W, and a repetition frequency of 8.27 MHz is obtained. To the best of our knowledge, this is the highest average power for generating a supercontinuum with an all-fiber structure based on the graded-index fiber. The effects of GRIN fiber length and different pump peak powers on the supercontinuum generation are also verified. The results showed that the graded-index multimode fiber can effectively obtain a supercontinuum with high power.

“…In addition, the effective shortwave extension of the SC driven by the GPI effect in the GRIN MMF requires a high pump peak power. Based on this reason, the maximum average output power of the SC generation from the GRIN MMF with an all-fiber structure is only maintained at about 2 W, as reported in 2022, and the corresponding spectrum covers the wavelength from 450 nm to beyond 2400 nm [17] .…”

Hundred-watt level all-fiber visible supercontinuum generation from a graded-index multimode fiber

View full text Add to dashboard Cite

A monolithic visible supercontinuum (SC) source with a record average output power of 204 W and a spectrum ranging from 580 nm to beyond 2400 nm is achieved in a piece of standard telecom graded-index multimode fiber (GRIN MMF) by designing the pumping system. The influence of the GRIN MMF length on the geometrical parameter instability (GPI) effect is analyzed for the first time, to the best of our knowledge, by comparing the SC spectral region dominated by the GPI effect under different fiber lengths. Our work could pave the way for robust, cost-effective, and high-power visible SC sources.

“…Supercontinuum sources have a wide range of applications in metrology [14], biomedicine [15], national defense and security [16], and environmental monitoring [17]. The richer nonlinear effects in MMFs benefit the generation of supercontinuum, so the study of supercontinuum in MMFs has attracted widespread interest [18][19][20][21]. Depending on the dispersion characteristics of the medium and the parameters of the pump source, the dominant nonlinear effects in the SCG will also be different.…”

Comparing with fused silica fiber, chalcogenide glass fibers are considered as an ideal platform for mid-infrared supercontinuum generation (SCG) because of its higher nonlinear coefficient and wider transparency window. Multimode fiber provides a new way to achieve special spectral characteristics in SCG by introducing intermodal interaction. We investigate the intermodal nonlinear phenomena associated with SCG in multimode chalcogenide fiber by numerically solving multimode generalized nonlinear Schrödinger equation. The results indicate that when the phase matching condition is satisfied, the intermodal interaction leads to the generation of dispersive waves at mid-infrared wavelength. Furthermore, intermodal and intramodal soliton collision are observed, and the bandwidth of the supercontinuum is increased by the intermodal interaction. These results may provide a new way for the generation of mid-infrared supercontinuum light source.
