摘要： The present invention relates to a device for amplifying a multi-wavelength laser beam, comprising:



a. An active laser medium having a front face suitable for receiving the beam to be amplified each time the same passes through the active laser medium, and a reflective rear face inclined with respect to the front face, the beam reflected by the rear face and refracted by the front face during the n-th pass being called the n-th useful beam, and
b. a first optical return unit arranged along the path of the first useful beam




and configured for returning the first useful beam on the front face for a second pass through the active laser medium so that the sub-beams of each wavelength, forming the second useful beam, are parallel to each other at the end of the second pass.

摘要： A folded compressor for a frequency shift system with a predetermined stretch ratio and which includes a compression network positioned to receive an input pulse and an output pulse of the compressor, mounted on a device for dynamic translation and rotation adjustment; a fold dihedral and at least one height adjustment dihedral, the compression network and the dihedrals being configured to form at least two stretched pulses on the compression network. The compression network is divided into two compression sub-networks with the same optical properties, mounted on the adjustment device: a first compression sub-network of determined length L for containing the stretched pulses, but not the input and output pulses, a second compression sub-network of length L2 for containing the input and output pulses, but not the stretched pulses, with L2

摘要： The present invention relates to a device for amplifying a multi-wavelength laser beam, comprising:



a. a first active laser medium having a front face and a rear face which is reflective, inclined with respect to each other at a first non-zero inclination, and
b. a second active laser medium having a front face suitable for receiving the beam reflected by the rear face and refracted by the front face of the first active laser medium, and a reflective rear face, inclined with respect to each other at a second non-zero inclination, the first inclination, the second inclination and the orientation of the second active laser medium being such that the sub-beams of each wavelength, forming the output beam of the second active laser medium, are parallel to each other at the output of the second active laser medium.
