Typical laser parameters for this experiment. Because of the lower pulse energies available to drive the 780 nm and 776 nm transitions in Rb, these beams were focused to a smaller diameter. Beam diameters are approximate because the beam profiles were irregularly shaped. Typical pulse durations were ∼5 ns for the ablation laser and 10–15 ns for the resonance lasers
