摘要： A system for the optical amplification of high-energy ultrashort light pulses, includes: an oscillator that can emit light pulses of sub-picosecond duration τ0, a pre-compensator, and a solid optical amplifier that can amplify the chirped light pulses. The pre-compensator has a negative group velocity dispersion, the pre-compensator being capable of generating negatively chirped light pulses, and the optical amplifier has a positive group velocity dispersion, the optical amplifier being disposed such as to receive and amplify the negatively chirped light pulses. The optical amplifier is configured such that the light pulses can induce a broadening of the spectral gain band Δν by self-phase modulation, such as to generate amplified, time-compressed light pulses of duration τ3, which is shorter than the duration τ=1/Δν of the bandwidth limitation of the optical amplifier.

摘要： A rare earth ion ultrashort laser source includes a resonant cavity having a first output face partially reflecting and a second reflecting face. The source also includes a first active material, which receives a pump luminous flux transmitted via a first solid laser pump source. The resonant cavity exhibits a length of optical path travelled by the pulses greater than 7.5 m so that the pulsed energy EL is greater than 100 nJ, the optical path including at least one passage in the active material and the ultrashort laser source includes elements for lengthening the resonant cavity thereby enabling to extend the length of the optical path travelled by the luminous pulses in the resonant cavity, the ABCD propagation matrix of the resonant cavity being close to the unit matrix so that the features of the luminous beam going back and forth in the resonant cavity remain unchanged.
