AbstractCoherent beam combining (CBC) is a method of enhancing laser power. It has recently transitioned to industrial applications, unveiling new possibilities in laser technology. CBC merges multiple laser channels from a single source, controlling their phase to create constructive or destructive interference. The optical phased array (OPA) and filled aperture methods exemplify CBC's advancements, enabling dynamic and precise beam manipulation. This technological evolution opens avenues for versatile applications in various industries, significantly advancing our capability to harness laser technology for complex tasks.
