Abstract

The operation of a Ti:sapphire-pumped, femtosecond optical parametric oscillator (OPO) based on the nonlinear material KTiOPO₄ is described. By empirically optimizing the parametric interaction geometry, we have extended the maximum idler wavelength beyond that reported for similar systems. The OPO typically produces 175-fs idler and signal pulses tunable in the ranges of 2.9–3.96 and 1.05–1.16 μm, respectively.
