Abstract

We present results from what we believe is the first reported example of an optical parametric oscillator based on periodically poled RbTiOAsO4. The oscillator is pumped by a femtosecond self-mode-locked Ti:sapphire laser and, with a single-grating a-mm-long crystal and one mirror set, a combination of pump and cavity-length tuning provided wavelength coverage from 1060 to 1225 nm (signal) and 2.67 to 4.5 mu m (idler). Average output powers were as much as 120 mW in the signal and 105 mW in the idler and interferometric autocorrelations recorded at signal and idler wavelengths of 1.1 and 3.26 mu m, respectively, imply pulse durations of 125 and 115 fs, respectively.
