Abstract

The effect of focus shift and its diameter changes due to high pump power level has been investigated theoretically in this paper. Two methods describing multi mode beam propagation have been developed and compared with the results of the experiment. The best coupling conditions of such laser beam with wave guide ( optical fiber) for a wide range of pump power have been discussed.
