Abstract
We have used the new Raman-induced phase conjugate (RIPC) technique to obtain strong Raman signals using picosecond laser pulses. We have obtained the picosecond RIPC spectra of carbon disulfide, benzene, nitrobenzene, and calcite. By delaying one of the interacting pump beams relative to the other pump and probe beams we were able to determine the intensities of the phase conjugate beams at the Stokes frequencies as a function of time with 20-ps resolution. These measurements show the potential of this technique to determine phonon relaxation times in condensed matter using shorter laser pulses.Keywords
