The device has a co-propagation unit to alternatively co-propagate a probe beam (R1) and a signal beam (R3) into amplifying fibers (30), and an interfering unit to interfere the probe and the signal beams at output of the fibers so as to define an interferogram. A matrix detector (50) e.g. charge coupled device matrix sensor, generates a digital hologram from the interferogram. A spatial phase modulator (60) i.e. LCD modulator, is supplied with the hologram to diffract the signal beam in order of 1 at input of the fibers. The modulator has cooling rate characteristics of phase law. |
