NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAsIt's got extended been predicted that the period difference between the sign and idler subharmonic outputs of the optical parametric oscillator (OPO) undergoes a random stroll procedure, just like the phase diffusion of the laser [one].Mo
