Abstract

The gain measurement method of radiation at Stimulated Raman Scattering (SRS) excitation in medium placed into transverse pump cavity /1/ has been developed and tested. On the third harmonic of iodine laser ISKRA-4 (λ=438 nm) values of gain coefficient (g) for transverse SRS (TSRS) radiation have been measured in benzene and in the frequency converter crystals (KDP, KD*P) grown following the traditional and rapid-growth technology, cut out by Type-II (9=60°). At the g measurement in crystals pumping wave was ordinary, the pumping and scattered wave vectors and the crystal optical axis were coplanar.
