Three pump spectrum system

I. Is it possible to observe a shift in coherent Raman scattering in the three-level system with A-type coupling We have done an experiment to obtain a femtosecond Raman gain spectrum in polydiacetylenes. The Raman spectrum is shifted to the red under increased pump (to i) intensity. By changing o>2> the amplification peak signal is to be shifted to lower frequency. If the optical Stark effect is observed, then, in principle, it should be possible to observe the effect of a high field on the coherent Raman spectrum (see Fig. 1). [Pg.444]

Raman Spectra. A Raman spectrum of the x XePtFg prepared in aHF, was recorded with a Halo Probe VPT System spectrometer (Kaiser Optical System, Inc., Ann Arbor, MI) using the 532 nm radiation of a Diode-Pumped, Solid-State (DPSS) Laser as exciting wavelength. It consisted of three lines at 657 cm (vs), 591 cm (s) and 480 cm (w). [Pg.83]
