Abstract

Summary form only given. We report on an efficient visible nanosecond optical parametric generator (OPG) of periodically poled lithium niobate (PPLN). This material is well suited for realizing an efficient OPG because of the high gain which can be achieved at pump intensities well below the crystal´s damage threshold. In our experiments we used as pump source the second harmonic 532 nm output of a diode-pumped Nd:YAG laser passively q-switched by a Cr/sup 4+/:GSGG crystal.
