Intracavity coherent beam combining of 21 semiconductor gain elements using SPGD

Coherent beam combining (CBC) allows for achieving high output power in a single diffraction limited beam. Here we report on intracavity CBC of 21-element semiconductor array with 81% beam combining efficiency out of a system maximum combining efficiency of 90%.
