Mid-infrared supercontinuum generation in tapered ZBLAN fiber with a standard Erbium mode-locked fiber laser
Optimized ZBLAN fiber for efficient and broadband mid-infrared supercontinuum generation through direct pumping at 1550nm
Highly Stable, All-fiber, High Power ZBLAN Supercontinuum Source Reaching 4.75 Âľm used for Nanosecond mid-IR Spectroscopy
Ultra-low-noise supercontinuum generation with a flat near-zero normal dispersion fiber
A pure silica photonic crystal fiber with a group velocity dispersion
() of 4 ps/km at 1.55 m and less than 7 ps/km from 1.32
m to the zero dispersion wavelength (ZDW) 1.80 m was designed and
fabricated. The dispersion of the fiber was measured experimentally and found
to agree with the fiber design, which also provides low loss below 1.83 m
due to eight outer rings with increased hole diameter. The fiber was pumped
with a 1.55 m, 125 fs laser and, at the maximum in-coupled peak power
(P) of 9 kW, a 1.341.82 m low-noise spectrum with a relative
intensity noise below 2.2\% was measured. The numerical modeling agreed very
well with the experiments and showed that P could be increased to 26 kW
before noise from solitons above the ZDW started to influence the spectrum by
pushing high-noise dispersive waves through the spectrum
