System and method of generation of a burst of laser pulses ultra-short high power and

摘要

The present invention relates to a system and method of generation of a burst of laser pulses ultra-short high power and comprising means for generating (1) of laser pulses (10) with a repetition period τ1, amplification means (2) comprising an optical amplifier medium (41), an optical cavity regenerative, injection means of the laser pulses (10) in said optical cavity regenerative and extraction means of the laser pulses of said optical cavity regenerative. According to the invention, the optical cavity regenerative has a total length such that the duration of an outward - return of each pulse in the said optical cavity regenerative is between n - 1 and n times the period τ1, where n is an integer number greater than or equal to two, said injection means are adapted to trap a burst of n laser pulses in the said optical cavity regenerative, said extraction means are adapted to extract said burst of n laser pulses of said optical cavity regenerative and the optical amplifier (41) is adapted to form a burst of laser pulses amplified (20).
