THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency era in OPGaAsIt has lengthy been predicted which the phase difference between the signal and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random walk system, just like the phase diffusion of the laser [1].The main-concepts de
