Frequency-resolved optical gating in the 1.55 um band via cascaded chi-2 processes
2005 (English)In: Journal of the Optical Society of America. B, Optical physics, ISSN 0740-3224, Vol. 22, no 9, 1985-1993 p.Article in journal (Refereed) Published
We investigate ultrashort-pulse interactions based on cascaded second-harmonic generation and difference-frequency generation and propose their use for frequency-resolved optical gating (FROG) at telecom wavelengths in a waveguide configuration. We show how a chi((2))-chi((2)) FROG device could allow the efficient characterization of ultrashort pulses, with time resolutions well beyond the limits normally imposed by walk-off effects on single-step chi((2)) FROG devices.
