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.

Pulse laser system that is temporally variable in terms of rhythm and/or amplitude

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.
