Abstract
A high repetition rate (4.46 kHz) picosecond laser system for time-res olved resonance Raman spectroscopy has been developed with a time reso lution of 10 ps. Probe beam pulses are tunable from 550 nm to 655 nm a nd the pump beam is generated by frequency doubling of the probe beam. Stabilized pulse energies at the sample are > 1 muJ/pulse (probe) and > 0.2 muJ/pulse (pump). Further tuning is possible using stimulated S tokes-Raman generation in dimethyl sulphoxide (2923 cm-1) which gives up to 35% energy conversion in the first and up to 7% energy conversio n in the second Stokes-Raman line.
