OPTICAL PARAMETRIC OSCILLATOR HAVING ADDITIONAL AMPLIFIER IN THE RESONATOR

摘要

A method for operating an optical parametric oscillator, wherein a first pump wave (1) is coupled into an optically non-linear element (3) in the propagation direction, wherein the pump wave (1) in the optically non-linear element (3) is separated at least in some regions into two waves, particularly a signal wave (4) and an idler wave (5), wherein one of the waves (4) is decoupled from the optical path and resonantly coupled into the optically non-linear element (3) by way of a regeneration section again in the propagation direction, wherein the wave (4) is actively amplified with respect to the amplitude thereof inside the regeneration section by means of an amplifier (9).
