Watts-level, continuous-wave pumped supercontinua, 1.06-1.7 mum, generated in a new low OH-loss PCF exhibit distinct spectral and noise dynamics when pumped with either high or low-intensity-noise 1 um sources. Applications to ultra-low-noise mum-scale OCT are analyzed.
Soft-glass photonic-crystal fiber is used to generate broad supercontinuum using an all-fiber-femtosecond laser. The bandwidth exceeds 1700 nm and has average powers in excess of 100 mW with 46-MHz repetition rate.
We report using short, heavily-doped active phosphate fiber for generation of picosecond pulses at 1.5 mum, with the peak power of 19 kW which results in a record-high aerial power density of 24 GW/cm2 in the fiber core.
We propose and demonstrate super-continuum generation from 1-mum ASE noise source instead of ultra-short pulses for the first time. With the amplified noise burst, super-continuum is generated over 500 nm with 23 dBm average power.
Using a two-stage design with ~1 m standard fiber followed by 10 cm of high-nonlinearity, fused silica fiber, super-continuum is generated from ~0.8 to 3.0 mum using amplified 2 ns laser diode pulses.
We introduce the design of an amplifying and nonlinear microstructured optical fiber. This unusual guide permits the nonlinear propagation with regeneration of the pump wave. The first fabricated structure is experimentally tested for supercontinuum generation.
Basic experiments of OPCPA with a Type I BBO crystal were conducted using the supercontinuum generated in a PCF. Tunable amplification bandwidth of 100 nm was demonstrated.
