HgGa2S4 Crystal Secrets
Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variance-frequency technology in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) determined by the Kerr-lens-method-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement
