Study on Far-Field Intensity Distribution of Fiber Laser Used in Coherent Beam Combination
In coherent beam combination with fiber lasers, the phases, amplitudes and polarization directions of each laser are different, influenced by manufacturing process, environment and others. The far-field intensity distribution and beam quality of lasers with coherent beam combination are studied and calculated. Numerical results show that the figure of far-field light distribution, the light intensity of peak value, and the power of the central region degenerate or trail off in varying degrees.
