The generation of femtosecond pulses in the visible region by optical parametric conversionusing a KTiOPO4 crystal is reported. An optical parametric oscillator pumped by a mode-locked Ti: sapphire laser generates 81 MHz-femtosecond pulses tunable in the 426-483 nm and 529-585 nm regions by intracavity upconversion. The conversion efficiency is as high as 44%.
