We demonstrated a very compact laser system providing continuous tunability at high-repetition rate in the visible range by pumping an optical parametric generator (OPG) of periodically poled lithium niobate (PPLN) with a frequency-doubled microchip laser operating at 532 nm. The 660-nm pulses were 0.55 μJ (with 40% of slope efficiency) and 500 ps, and the threshold was only 1.3 μJ (75 MW.cm-2).
