THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

and operating circumstances for the practical design and style of substantial power femtosecond optical parametric oscillators with excitationWe report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser given that the pump source. By deploying a novel cascaded
