NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency era in OPGaAsWe report on the femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) depending on the Kerr-lens-manner-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a fe
