The authors describe a diode‐pumped Nd:YAG laser that produces 920 mJ output energy pulses with a pulse duration of 76 ps at 200 Hz pulse repetition rate. Second‐harmonic generation with a pulse energy of 730 mJ and pulse duration of 63 ps was obtained by using LiB 3 O 5 crystal with II‐type phase matching. The output beam divergence was about 1.5 × DL (the diffraction limit) and 1.9 × DL for 1064 and 532 nm wavelengths, respectively.
