Abstract
We report octave-spanning super-continuum generation in a silica photonic crystal fiber (PCF) pumped by a compact, efficient, mode-locked all-normal dispersion Yb:fiber laser. The laser achieved 45% optical-to-optical efficiency by using an optimized resonator design, producing chirped 750 fs pulses with a repetition rate of 386 MHz and an average power of 605 mW. The chirped pulses were compressed to 110 fs with a loss of only 4% by using multiple reflections on a pair of Gires-Tournois interferometer mirrors, yielding an average power of up to 580 mW. The corresponding peak power was 13.7 kW and produced a super-continuum spectrum spanning from 696-1392 nm. (C) 2012 Optical Society of America
