title: High-repetition-rate high-average-power 300-fs KrF/Ti:sapphire hybrid laser.
abstract: We have developed a 1-kHz KrF/Ti:sapphire hybrid laser system. Average power was 7 W at 248 nm with a pulse width of 300 fs. A kilohertz Ti:sapphire regenerative amplifier at a wavelength of 745 nm is also described.
