Results on investigating physical properties of some new nonlinear crystals are presented. Comparative analysis of frequency converters based on them is given. Second harmonic generation of lasers, which is the first implemented and minutely described frequency conversion in and crystals with sufficient efficiency for its quantitative description, is analyzed. It is shown that application of and for direct (single-stage) frequency conversion of femtosecond lasers into the mid-infrared has advantages over multistage setups and direct frequency conversion in The possibilities of applying frequency converters based on the investigated crystals in lidar systems to analyze atmospheric composition are considered.
