| Optical arrangement for the generation of ultraviolet third-harmonic light. A microchip Nd:YAG crystal embraced by a Cr+4:YAG slab as Q-switch element is used for a fundamental pump (red arrow). A type II KTiOPO4 crystal is used to generate the second-harmonic radiation (green arrow) while the third-harmonic beam (blue arrow) is generated by a type-I β -BaB2O4 crystal. |
