Abstract
In the present optical parametric oscillator (OPO)-system the seed radiation is generated by a BaB2O4 (BBO)-OPO with a wide mode spacing. This OPO with a 2.5-mm-long BBO crystal in a 3.6-mm-long flat-flat mirror resonator is pumped by an injection seeded frequency tripled Q-switched Nd:YAG laser. Despite the short crystal the OPO efficiency exceeds 25% at a 355-nm-pump-pulse energy of 30 mJ (3 times above threshold)
