LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Depending on our research, we also suggest a fresh plan for improvement of compact significant-energy OPO sources applying MgO:PPLN chips of comparatively limited lengths and large cross-sectional spot.We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) based on the Kerr-lens-method-locked Ti:sapphire l
