We report the demonstration of a 250-MHz mode-locked, intracavity frequency-doubled, diode-pumped Nd:YAG laser. The laser produces 520-psec pulses at an average power of 76 mW and a wavelength of 532 nm. The laser has an electrical-to-optical efficiency of 1.43% and was operated both cw and mode locked. Mode locking increased the average output power by 60% and eliminated noise due to modal competition.
