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

摘要

The invention relates to a system based on recombination by superposition using a diffractive optical element DOE (1) for combining the beams. According to the invention, a diffractive optical assembly (21) is disposed upstream of this diffractive optical element in order to enable combination efficiency at ultrashort pulse speed to be optimized by means of an appropriate imaging system.
