THE 2-MINUTE RULE FOR HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency era in OPGaAsWe report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) determined by the Kerr-lens-method-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprisin
