A laser pumped zig-zag dye laser operating at 568 nm with a pulse length {approximately} 2 {micro}s has been scaled to high power using a MOPA configuration. Pulse energies in excess of 7 J with beam quality < 2 XDL have been achieved under repetitively pulsed, 10 Hz operation. RMS jitter was measured as 0.12 of a 1 XDL spot. The device has operated with over 70 W output for runs up to 5 s. Substantially longer run times and output powers are possible. This device represents an advance in dye laser capabilities. Improvement in pointing accuracy of better than an order of magnitude have been demonstrated. In addition, an improvement in beam quality by about an order of magnitude has been achieved compared to other dye lasers operating in this power range.
