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.

Schematic diagram of the OPO showing the location of the CaF2 output coupler (M3) through which the idler is extracted after each synchronously pumped pass of the signal. The pump, the signal, and the idler are designated P, S, and I, respectively. The inset shows the directions of the wave vectors kp, ks, and ki along with the direction of the Poynting vector ss of the signal wave with respect to the crystal xz axes.
