Abstract: Disclosed is a system and a method for generating high-power laser pulses with very high repetition rate. The laser system includes an oscillator capable of generating a source laser beam including a series of sources pulses with femtosecond or picosecond duration at a first repetition frequency no lower than 800 megahertz and an optical amplifier system suitable for receiving and amplifying the series of source pulses at a second repetition frequency that is equal to or a multiple of the first repetition frequency, the multiple being a non-negative integer greater than or equal to two, so as to generate a series of laser pulses with very high repetition frequency.

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 method for cutting dielectric or semiconducting material with a laser. The method includes the following steps: emission of a laser beam including at least one burst of N femtoseconds laser pulses; spatial separation of the laser beam into a first split beam having a first energy, and respectively, a second split beam having a second energy; spatial concentration of energy of the first split beam in a first zone of the material, respectively, of the second split beam in a second zone of the material, the first zone and the second zone being separate and staggered by a distance dx; and adjustment of the distance between the first zone and the second zone in such a way as to initiate a straight micro-fracture oriented between the first zone and the second zone.

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.
