Ti:sapphire-pumped solid state source of high-repetition-rate tunable in the visible
- Cornell Univ., Ithaca, NY (United States). School of Applied and Engineering Physics
The authors report on the generation of high-power, high-repetition-rate femtosecond pulse tunable in the visible by intracavity frequency-doubling of a KTiOPO{sub 4} (KTP) femtosecond optical parametric oscillator (OPO). The KTP OPO is synchronously-pumped by a self-modelocked Ti:sapphire laser producing pulses of 225 kW peak power at a repetition rate of 81 MHz (115 fs pulsewidth), and a center wavelength of 790 nm. Using a 1.5-mm-thick KTP gain crystal and a 50 {micro}m {beta}-BaB{sub 2}O{sub 4} frequency-doubling crystal, they achieve up to 240 mw of sub-100 femtosecond pulses tunable in the range of 580 to 660 nm. The potential tuning range of the frequency-double KTP OPO, when pumped at 790 nm, is approximately 500 to 750 nm.
