High-capacity fiber lasers represent a fusion of two cutting-edge laser technologies: advanced optical fibers and semiconductor diodes. These lasers employ semiconductor diodes to serve as the primary light source, which in turn energizes the active fiber. Within the optical fiber, the laser beam is generated and subsequently transmitted through a flexible, resilient cable. This process involves the blending of top-quality active fibers with rare-earth ions, resulting in the creation of a highly efficient, minute core capable of generating potent lasers, reaching one kilowatt in power output, all while maintaining superior beam quality. IPG leverages a range of proprietary technologies to consistently produce high-powered (kilowatts) fiber lasers to cater to both the existing and potential market demands.
