and operating circumstances for the practical style of large energy femtosecond optical parametric oscillators with excitationWe report over a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arra
