LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency era in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arrangement, comprising

Depending upon the distribution coefficient amongst Resolution and crystal, impurity/dopant depletion or enrichment could occur. This provides temporal inhomogeneity of dopant concentration for the developing crystal, causing spatial inhomogeneity of crystal Homes. Therefore, to obtain crystals with superior uniformity, an improved thermo-hydrother
