Zusammenfassung:An innovative scheme of a fiber optical parametric oscillator with two-arm synchronous pumping is presented. Numerical simulation is performed in a wide range of parameters. The domains of existence of stable regimes of generation of parametric pulses are found versus the peak power of pump pulses and their time overlap with parametric pulses (relative delay) for detuning of the carrier wavelengths of the pump pulses in the arms of up to 1 nm and lengths of photonic crystal fibers of 33 and 43 cm. It is shown that such two-arm synchronous pumping makes it possible to increase the maximum energy of the output pulses to 57 nJ (by almost a factor of two compared to the linear scheme) and works like offset filters of the Mamyshev oscillator, making it possible to obtain pulses with parameters inaccessible for alternative schemes.
