Fine Resolution of Energy Structures of Large Molecules in Solution by Coherent Population-Grating Spectroscopy

Hirotoshi Souma, C. Horie, Masayuki Hoshi +1 more

We have succeeded in observing finely resolved spectra in the spectral regions of absorption and emission bands of cresyl violet in ethanol, by means of population-grating spectroscopy based on four-photon parametric mixing. The inhomogeneous width is investigated in terms of the excitation frequency dependence. The energy separation and the homogeneous width are also analyzed by assuming that the observed fine bands consist of several Lorentzian lines. It is revealed that the observed spectra reflect the detailed vibrational and vibronic structures of molecules. This high-resolution spectroscopy can be readily applied to more general disordered systems in the condensed phase.

Four-photon parametric frequency selection in wide stimulated emission lines

A P Veduta, B. P. Kirsanov

It is shown theoretically that the interaction between coherent light waves may give rise to periodic structures of parameters such as the refractive index, the absorption, and population inversion, etc. These structures can act as frequency-selection elements of the diffraction grating or the multilayer mirror type. Numerical estimates are obtained for some cases which satisfy formally the phase matching conditions for the four-photon interaction. Particular consideration is given to the case of coherent pumping of a dye-solution laser in which the frequency of the laser emission within a wide line can sometimes be altered.
