"The goal of our work is the development of intracavity synchronously pumped optical parametrical oscillator (OPO), generating two trains of picosecond pulses inside a single cavity. These trains have the same repetition rate but they are independent and can differ in phase and carrier frequency. This allows to determine very precisely the phase difference between them which is possible to use in all sensor applications where the measured physical quantity is converted into phase difference between two counter-circulating pulses. We designed a synchronously pumped OPO with nonlinear crystal (MgO:PPLN) for parametric generation inserted inside a linear resonator of a modelocked diode pumped Nd:YVO4 laser. We observed that the OPO could generate in three regimes: the desired dual pulse operation when the pump pulse produces parametric waves during both forward and return passes through PPLN crystal." .
