    Abstract: Disclosed is a system for generating a spatially localized, high-intensity laser beam, including: a laser source designed to generate a burst of N laser pulses with a duration of less than or equal to one picosecond, the N laser pulses having a first repetition frequency greater than or equal to 0.5 gigahertz; a resonant optical cavity designed to receive and store the burst of N laser pulses, the resonant optical cavity being designed to focus the burst of N laser pulses in an interaction region of the resonant optical cavity; and a servo control system designed to control the first repetition frequency relative to the roundtrip distance in the resonant optical cavity, such that the N pulses of the burst are superimposed temporally and spatially by constructive interferences in the interaction region so as to form one giant ultra-short and high-energy pulse.

    Abstract: Disclosed is a nonlinear optical system for generating or amplifying light pulses by N-wave mixing, including a nonlinear optical medium suitable for receiving at least one first light pulse and one second light pulse. The system includes a fast modulation device for modulating a time delay between the second light pulse and the first pulse light in the nonlinear optical medium, the time delay modulation device being placed upstream of the nonlinear optical medium, and the time delay modulation device being modulated at least between a first delay value and a second delay value, so as to modulate the generation or amplification of a light pulse by N-wave mixing of the at least one first light pulse et one second light pulse in the nonlinear optical medium.

    Abstract: Disclosed is a laser system including a source, for generating a source signal, and an optical amplifier system. The laser system includes a pulse selection or variation device configured to select or vary the source signal so as to form a main signal composed of one or more light pulses. The main signal is temporally variable in terms of rhythm and/or amplitude. The laser system is configured to inject the main signal and a secondary signal into the optical amplifier system. The secondary signal is varied on the basis of the temporal variation in terms of rhythm and/or amplitude of the main signal so as to stabilize the power stored in the optical amplifier system in a time-dependent manner, and the laser system is configured to spatially separate the amplified main signal from the amplified secondary signal.
