Opis:: We have discussed new optical potentialities in acentric Gd$\text{}_{2}$(MoO$\text{}_{4}$)$\text{}_{3}$ and LaBGeO$\text{}_{5}$ laser crystal-hosts having simultaneously relatively high χ$\text{}^{(2)}$ and χ$\text{}^{(3)}$ nonlinear susceptibilities. In particular, we show experimental results on efficient multiple Stokes and anti-Stokes stimulated Raman scattering and Raman induced four-wave mixing, as well as second harmonic generation with Cerenkov-type phase matching.

Opis:: Developments of three new time-resolved vibrational spectroscopies and their applications to electronically excited states are reviewed. Transformlimited picosecond time-resolved Raman spectroscopy has been used to study the vibrational dynamics of trans-stilbene in the lowest excited singlet state. Picosecond time-frequency two-dimensional multiplex Coherent Antistokes Raman Scattering spectroscopy has been used to probe the structure of diphenylacetylene in the lowest and the second lowest excited singlet states. Nanosecond time-resolved dispersive infrared spectroscopy has detected the singlet and triplet intramolecular charge transfer states of 4-(di-methylamino)benzonitrile. Strong evidence for a charge transfer structure has been obtained.

Opis:: Raman piezospectroscopy of high quality 6H-SiC crystals is presented. The crystals used in experiments were grown by the seeded physical vapor transport method. Uniaxial stress up to 0.9 MPa, obtained using a spring apparatus, was applied along [11-20] and [10-10] directions. It was found that the application of uniaxial stress led to different energy shifts of the observed phonon excitations in the investigated 6H-SiC crystals. The obtained pressure coefficients vary in the range 0.98-5.5 $cm^{-1}$ $GPa^{-1}$ for different transverse optical phonon modes. For longitudinal optic phonon modes pressure coefficients in the range 1.6-3.6 $cm^{-1}$ $GPa^{-1}$ were found. The data obtained could be useful in evaluation of local strain fields in SiC based structures and devices including epitaxial graphene.
