Abstract :
In this paper, a diode-pumped Yb-fiber master-oscillator power multimode-amplifier associated to a multimode-to-singlemode converter using an infrared sensitive photorefractive crystal was demonstrated. The complete analysis of the different beams spatial qualities was done and experimental results with a numerical simulation of the system was also compared.
