Abstract
The invention relates to a parametric oscillator (1) for generating ultra-short pulses. The system (1) comprises a resonator (10) having an optical axis (11), an amplifier crystal (9) arranged in the resonator (10), and a pump laser system (4) for generating pump laser radiation (5) comprising pump photons, said pump laser radiation being directed onto the amplifier crystal (9). The invention is characterized in that the amplifier crystal (9) is an optically non-linear crystal configured for generating a signal photon and an idler photon from a pump photon by means of an optical-parametric process, wherein the resonator (10) is arranged in such a way that a signal pulse formed from the signal photons leaves the amplifier crystal (9) along the optical axis (11) of the resonator (10), and wherein dispersion compensation members for at least partially compensating the dispersion of the radiation circulating in the resonator (10) are provided. The invention also relates to a method for generating ultra-short pulses or the associated mode comb by means of such a parametric oscillator (1).
