SYSTEM FOR SPATIAL RECOMBINATION OF ULTRASHORT LASER PULSES BY MEANS OF A DIFFRACTIVE ELEMENT

摘要

The proposed solution is based on recombination by superposition using a diffractive optical element DOE to combine the beams. According to the present invention, an optical diffractive assembly is disposed upstream of this diffractive optical element, making it possible, via a suitable imaging system, to optimize the coupling efficiency in the ultrashort pulse regime.
