High-repetition-rate infrared-pump, infrared-probe spectrometer.
A method for generating two independently tunable 25-ps infrared pulses at 500 Hz was demonstrated. The apparatus is based on two dye lasers, a regenerative amplifier, and two lithium iodate optical-parametric amplifiers. Using the pump-probe technique, we measured the lifetime of the excited vibrational-state absorption of tungsten hexacarbonyl in solution.
