Abstract

OPG emission in long periodically-poledMgO:LiNbO<sub>3</sub> crystals pumped by a Q-switched Nd:YVO<sub>4</sub> laser was characterized. The experimental results obtained for small gain-length product (<i>g<sub>0</sub>L</i><10) are in excellent agreement with quantum mechanical model calculations.
