Femtosecond Luminescence Spectroscopy with 60 fs Compressed Pulses.
01 January 1988
We report compression of the pulses from a synchronously pumped Rh 6G dye laser to 60 fs using a fiber-prism compressor. Average power in excess of 150 mW has been obtained. Using this compressed laser and the sum-frequency-generation technique, we have demonstrated the capability of measuring luminescence spectra with 65 fs time resolution. Initial results on GaAs and AlGaAs are presented.
