NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency era in OPGaAsOne particular observes a dramatic rise in generation of the 2nd harmonic and also the demodulation indicators vs . the pump wave amplitude. A clear correlation exists amongst these nonlinear signatures and the amount of damages. Preliminary determi
