We performed two-color resonant two-photon ionization (2C-R2PI) using an EKSPLA PL2251 Nd:YAG laser system producing ~30 ps pulses. The 355 nm output pumped a tunable optical parametric generator (OPG) (UV output of ~100 μJ). Leftover 1064 nm and 532 nm light from the pump were combined to generate the 5 th harmonic at 213 nm (0.3 mJ), to be used as the ionization pulse. We also used the 193 nm output from a GAM excimer laser to ionize (2 mJ per pulse, 8 ns pulse width).
