Abstract
We describe configurations of a novel synchronously pumped femtosecond optical parametric oscillator based on the crystal RbTiOAsO4 and operating with a signal-pulse-repetition frequency as high as 344 MHz. Average signal powers as high as 600 mW and pulse durations of 78 fs are demonstrated at a wavelength of 1.25 µm, and a characterization of the signal output using frequency-resolved optical gating implies asymmetric near-sech2(t) intensity-profile pulses with significant amounts of spectral cubic phase.Keywords
