STABILIZED FEMTOSECOND PULSED LASER AND STABILIZATION METHOD

摘要

The present invention relates to a high-power femtosecond pulsed laser, said laser comprising: a source able to generate a series of input laser pulses having an envelope frequency and a carrier frequency; chirped pulse amplification means; and, means for controlling the phase drift between the envelope frequency and the carrier frequency of the output laser pulses. According to the invention, said means for controlling the phase drift between the envelope frequency and the carrier frequency comprise electro-optical phase-modulation means that are placed on an optical path of the chirped pulse amplification means in order to stabilise the phase drift between the envelope frequency and the carrier frequency of the output laser pulses as a function of time.
