Abstract
Conjugate Dammann grating based coherent beam combing technique is an efficient way of combining phase-locked laser array into one high-power high beam-quality laser output. In this paper, this technique is applied to the combination of two-dimensional phase-locked array of solid state laser beams. Square apertures that could increase the areal fill factor of 21.5% are adopted. Numerical and experimental simulations of the combinations of 4Ã4 and 5Ã5 2D coherent laser arrays are carried out. The influences of manufacturing and positioning errors of the conjugate Dammann gratings to the beam combining efficiency are also discussed in detail.
