    "abstract": "We report the first demonstration to our knowledge of a continuously tunable\npicosecond laser operating around 1 MHz. The emission can be tuned from 640 to\n685 nm and the repetition rate from 200 kHz to 1 MHz with a pulse duration of\nless than 200 ps. The system is based on a Nd:YVO4 passively Q-switched\nmicrochip laser providing a few tens of nJ per pulse. Two cascaded stages of\namplification are then used to increase the pulse energy to several microJ .\nThe frequency doubled radiation is then used to pump a\nperiodically-poled-niobate-lithium (PPLN)-based optical parametric generator in\nan all-solid-state architecture. 20 nJ of tunable signal radiation are\nobtained. We also demonstrated 300-ps pulses generation in the UV (355 nm) at 1\nMHz.",
