M. Mehendale et al., Method for single-shot measurement of the carrier envelope phase of a few-cycle laser pulse, OPTICS LETT, 25(22), 2000, pp. 1672-1674
The interference between different harmonics of a few-cycle optical pulse i
n the region of the spectral overlap is sensitive to the phase of the optic
al carrier inside the pulse envelope. Near-surface third-harmonic generatio
n from Si(001) combined with second-harmonic generation in a 10-mum-thick b
eta -barium berate crystal produces sufficiently strong harmonic emission f
or single-shot measurement. We propose using this technique to measure the
carrier envelope phase of high-energy 5-fs pulses. (C) 2000 Optical Society
