We have developed a powerful and efficient mode-locked and /ital Q/-switched diode laser pumped Nd:YAG laser. Mode locking has been accomplished using intracavity frequency modulation (FM) to produce continuous-wave mode-locked pulses of 12 ps duration. Acousto-optic pre-lase /ital Q/ switching has produced a train of pulses of about 25 ps average duration at a repetition rate of 360 MHz in an envelope of 75 ns duration. When pumped with a 500 mW diode laser array, the energy in the /ital Q/-switched envelope was 15 /mu/J giving a peak power in the largest pulse of 19 kW. The laser has been frequency doubled in a crystal of potassium titanyl phosphate (KTP) with an efficiency of 36%. The doubled radiation at 532 nm has been used to synchronously pump a mode-locked rhodamine 6G dye laser to produce a train of tunable pulses. The pulse duration of the dye laser was 3.2 ps and the peak power of the largest pulse in the train was 10 kW.
