Abstract

The anti-Stokes Raman laser is a perspective way to develop laser source to produce radiation with shorter wavelength. It is known that the effective anti-Stokes radiation can be obtained only under appropriate phase matching angle which is determined by the following phase matching condition K_a = 2K_P - K_s. Here K_p> K_s and K_a are the pump, 1^st Stokes and 1^st anti-Stokes wave vectors correspondingly. In barium nitrate Raman crystal these angles were measured to be about 2° out of the crystal for 532 nm pump [1]
