Abstract

We report both extracavity and intracavity simultaneous second-harmonic generation and compression of pulses at 1.25 μm from a synchronously pumped RbTiOAsO4 -based optical parametric oscillator, using an aperiodically poled crystal of KTiOPO4 . The 290-fs input pulses were temporally compressed to 120 fs, with average output powers as great as 120 mW. The experimental results are compared with a numerical model that uses data obtained by characterization of the input pulses by use of the frequency-resolved optical gating technique.
