Abstract
A Ti:sapphire-pumped intracavity-doubled optical parametric oscillator generates up to 240 mW of sub100 femtosecond pulses tunable in the visible. The OPO consists of a 1.5 mm thick KTP crystal configured in a ring cavity which is synchronously pumped by a self-mode-locked Ti:sapphire laser. Intracavity doubling of the OPO is accomplished by inserting a .beta.-barium borate crystal into an additional focus in the OPO cavity. Continuous tuning of the second harmonic signal from 580 to 657 nm is obtained, with a potential tuning range being approximately 500 to 800 nm.
