Sampling device of a laser beam of High Energy and large associated to a Compressor

摘要

Set of Sampling and Measurement of a Pulsed laser beam of High Energy and large diameter, to be associated to a Compressor (3) presents a useful opening,The whole Device comprising: a sampling of this Beam, designed to be placed upstream of a Compressor (3),This device is provided with a sampling of diopter (44) to transmit T% adequate sampling of a Pulsed laser beam to compress.Where t is higher than 90 and reflect (1 - t)% of the Pulsed laser beam to compress this Beam, the reflected beam as sampled- a afocal Optical System (42) suitable for reducing the size of the beam sampled and designed to be placed upstream of the compressor (3),A device (45) reinjection provisions after the afocal Optical System (42),(45) The reinjection device designed to be placed upstream of the compressor (3) and Inject the beam into the useful Aperture sampled reduced compressor (3),(43) and a device of measuring Beam sampled and compressed to be positioned downstream of the compressor (3).
