Gorelik, A. Kudryavtzeva, V. Orlovich, M. Tareeva, N. Tcherniega, A. Vodchits] We investigate stimulated scattering of light in globular photonic crystals infiltrated by water. Excitation of stimulated scattering of light is realized using powerful ultrashort (70ps) laser pulses with an energy of 35mJ and a frequency repetition of 15Hz. We use the second-harmonic generation (532nm) of the master oscillator and amplifier with a wavelength of 1064nm. The photonic crystals under study are artificial opals filled by water or ethanol. We characterize the sample structures employing an electronic microscope along with the fiber-optics reflectance-spectroscopy technique. Photonic crystals have a stop band near the spectral positions of the exciting line (532nm) and the first satellite of stimulated Raman scattering of light in water (649nm). We observe a substantial reduction of the threshold of stimulated Raman scattering of light in water-infiltrated artificial-opal matrices in comparison with that of pure water. Such a reduction is explained as the result of a sharp increase in the photonic density of states near the stop-band edges of investigated photonic crystals. The reduction in the threshold of stimulated Raman scattering of light in water-infiltrated artificial-opal matrices opens up the opportunity to observe stimulated Raman scattering in numerous water media, including water solutions, biological and medical samples, heavy waters, and others.
