Generation of carrier-envelop-phase stabilized 3.3-fs optical pulses

The carrier envelope phase (CEP) stabilizer of the 12-fs Ti:sapphire oscillator with chirp-mirror compensation consists of the so-called f-to-2f interferometry, the phase-detection and phase-locking electronics with a frequency divider of f/sub rep//4 and the controller of the CW pump power through a feedback based on the acousto-optic modulator (AOM). Another frequency divider of f/sub rep//72000 was used to derive the multi-pass amplified pulse repetition rate through a Q-switched trigger of pump pulses. By this system combined with the CEP measurement technology, the new field of the electric-field wavepacket photonics will be opened.
