Abstract :
The estimation of allowable beam loading of nonlinear optical crystals can be carried out on energy density of the focused laser radiation it microsecond pulses of radiation. This magnitude should d not exceed 15-20 J/cm2 for KH2PO4 (KDP) crystals. It is necessary to apply crystals of large length that promotes rather high SHG efficiency and long-term operation of system under conditions that are typical for flash lamp pumped (FLP) dye lasers (DL). There the requirements were determined to the main parameter´s of FLP DL radiation that provide effective SHG by use of known nonlinear-optical crystals.
