High pulse energy, all-fiber supercontinuum source using tapered photonic crystal fibers (Conference Presentation)

Paper Abstract

We report a high pulse, all-fiber supercontinuum source generated by pumping 2 ns long pulses at 100kHz from an ytterbium-doped fiber amplifier (YDFA) into a 15 m tapered photonics crystal fiber (PCF). The YDFA operates at 1066 nm, and the zero-dispersion wavelength of the PCF is at 1040 nm. The PCF is a 15 µm core at the input, tapered down to 5 µm at the output. The tapering is done such that the core-pitch ratio is maintained along the length of the fiber used. The resulting supercontinuum spans from 450 nm to 2400 nm, with a total pulse energy of more than 7uJ. The supercontinuum covers the visible spectrum making it useful for applications that require substantial pulse energies such as photoacoustic tomography.
