Filled-aperture coherent summation technique for multiple high average power laser beams

Summary form only given: Single-detector, filled-aperture coherent beam combining technique for CW and high repetition rate ns pulse laser beams has been proposed. Proof of principle experiments have been performed for four beams. The combining efficiency for the present laser system was estimated to be 0.9. The proposed CBC technique can accommodate kW level average power beams, be integrated into various MOPA architectures and perform with high speed and accuracy.
