Abstract

We represent the results of a complex optical, lasers, and spectroscopic studies of organic nonlinear crystals: the lithium formate monohydrate -LiCOOH*H₂O (LFM), the urea - CO(NH₂)₂, the dimethylurea - CO(NHCH₃)₂, the KLiH₄C₄O₆ and the potassium malate acid - KH₅C₄O₅. These crystals thanks to nonlinear properties and high optical durability widely used as a generators of harmonics and as optical parametric oscillators (OPO).From the one hand the study of SRS these crystals is vary impotent task because as known the principal reason which limited the OPO efficiency is SRS, from the other hand the SRS presented independent interest for generation of the new laser frequencyes.
