Red pulses with >30 mJ energy and < 0.6 nm bandwidth have been demonstrated using a type 2 phase matched optical parametric oscillator pumped at 532 nm. A symmetrical signal beam with beam diameter-divergence product of 3 mm·mrad was obtained by applying KTA and BBO crystals in the same resonator.
Key words: Optical parametric processes / high energy / beam quality / walk-off
