THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency era in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser given that the pump supply. By deploying a novel cascaded intracavity arrangement, comp
