AMPLIFYING AND PHASING DEVICE FOR POWER LASER SOURCES

摘要

The invention concerns an amplifying and phasing device for power laser sources comprising, at the output (1) of a laser source to be amplified, a spatial dispersion device (2) followed by N amplifying optical fibers (6), N being a function of the desired gain for the amplifier device and of the gain of optical fibers, a signal sampling device at the output of each of said optical fibers (9) followed by a wavefront analyzing and phase correcting device (10) connected to a spatial modulator (11) interposed between the dispersive device and the inputs of the N optical fibers.
