A high-power frequency-doubled Nd:YAG laser using amplifiers in slab geometry has been developed to pump a dye laser as part of a spectroscopy experiment. The necessary fast synchronization within the experiment required a special pumping method that resulted in a more than four times higher average thermal load of the Nd:YAG crystals than it would be in a system with no synchronization requirements. Under these conditions, the laser was routinely operated at a repetition rate of 20 Hz, delivering about 600 mJ at 532 nm divided among four beams, which corresponds to a frequency conversion efficiency of more than 60%. Compared to a system with amplifiers in conventional rod geometry, the use of the slab geometry in the amplifiers made possible an increase of the repetition rate by a factor 4.
