Patent ID: 11362483

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.
