Application of a wavelength-independent autocorrelator for characterization of sub-100 femtosecond UV pulses from an OPA
POSTER
Abstract
The tunable output in the UV and DUV region from an optical parametric amplifier (OPA) is used to perform multicolor pump-probe experiments. For this purpose, the OPA output pulses are compressed by a prism compressor. We demonstrate a FROG-type autocorrelator, based on two-photon absorption in a thin crystal, to characterize the compressed sub-100 femtosecond UV and DUV pulses over a broad wavelength region.
