Ruebel, G. Anstett, J. L'huillier] The generation of tunable mid-infrared picosecond laser radiation in a synchronously pumped optical parametric oscillator (OPO) based on periodically poled lithium niobate (PPLN) is reported. Numerical calculations were used to optimize the crystal length in order to balance the parametric gain and the absorption losses in the high-absorption regime of lithium niobate. Due to the numerical results, the system was systematically optimized for the mid-infrared output power. An output power of 1.1W at 4.5μm and of more than 3W at 3μm were achieved for 6-ps-long pulses with a repetition rate of 160MHz and an M2<2. Springer-Verlag, 2010 Ruebel F.
