A SECRET WEAPON FOR HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency era in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser as the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a
