摘要: 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 a 1.5 mm thick KTP crystal configured linear or ring cavity which is synchronously pumped by self-mode-locked Ti:sapphire laser. Intracavity doubling accomplished inserting β-barium borate into an additional focus cavity. Continuous tuning second harmonic signal from 580 657 nm obtained, with potential range being approximately 500 800 nm.
