Abstract
To avoid the phenomena of self-focusing and astigmatism of the amplified wave, the amplifier includes in succession: an input segment having an input waveguide adapted to guide a monomode input wave; a diffraction segment comprising a first medium transparent to said monomode input wave and adapted to widen it; a collimation segment; and an amplification segment having an amplifier waveguide wider than said input waveguide. The amplifier can provide a high-power laser source supplying a widened fundamental mode wave. Application to producing waves for pumping fiber optic amplifiers.
