Abstract
The invention relates to a device for a laser blocked-mode, especially for a pulsed laser, comprising a cavity resonator () which is defined by a first mirror () and a second mirror (), and fitted with an amplifying active laser medium () for the amplification of a beam of laser radiation of a fundamental frequency (ω1) and a solid, non-linear optic means () comprising at least said second mirror () for reversible conversion of the radiation of the fundamental frequency (ω1) into radiation of a harmonic frequency (ω2) whereby said non-linear optic means () has a reflection factor which increases with the intensity of the radiation of a fundamental frequency. The invention is characterized in that said device also comprises a solid intensity limiter () in the cavity resonator (), whereby the transmission factor of the laser radiation decreases with the intensity of said radiation. The invention also relates to a method for a laser blocked-mode, especially for a pulsed laser, using said device.
