Figure 1: Top view of the experimental setup, depicted (a) and sketched (b). An adequate portion of the pulse energy was split off from the Nd:YAG-laser for OPO pumping. The residual energy generated using the commercial harmonic generator modules. The OPO signal and beams were combined in front of the SFG stage.
