P. 98101O-1-98101O-7Abstract: Double peak phase matching was recorded during experimental study of parametric frequency converters based on GaSe, its solid solutions crystals like GaSe1-xSx and ZnGeP2. Its physical origins are identified as presence of twin, large difference between cut and PM angles, self-heating effect at appropriate conditions, mismatched second (Φ) phase matching angle and microdefects. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
