We demonstrate a new kind of picosecond laser source in the UV at high repetition rate. This system is based on only passive, compact and simple elements: a microchip laser and a very efficient multipass amplifier both pumped with recently developed high brightness laser diodes. This all- solid-state laser has been optimized for delivering, at a high repetition rate -45 kHz-, sub-nanosecond pulses at the wavelength of 355 nm with an energy per pulse close to 1 (mu) J (or equivalently 38 mW average power). This source is- -to our knowledge--the first totally passive, 300-ps UV laser source at this high repetition rate.
