Fourth-Harmonic Generation of High-Repetition Femtoscond Ti:Sapphire Laser by a BBO Crystal

Abstract:

Fourth-harmonic generation of an 82MHz femtosecond Ti:sapphire laser oscillator has been demonstrated by the sequential sum-frequency mixing design with BBO crystals. Frequency quadrupling of a mode-locked Ti:sapphire laser results in maximum average power of 7mW at 82 MHz with the pulse duration of 200fs. The shortest wavelength achieved is 196.5 nm.
