LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency generation in OPGaAsIt has extended been predicted that the phase distinction between the sign and idler subharmonic outputs of the optical parametric oscillator (OPO) undergoes a random stroll course of action, just like the section diffusion of the lase
