Modern defense, space, industrial and scientific applications increasingly require laser power levels far beyond what a single laser source can deliver, at least without significant degradation of beam quality. High beam quality is of crucial importance for many applications that rely on excellent beam focusability or require the delivery of high laser power over long distances with a minimal beam divergence angle. Examples include laser fusion, laser communications, defense applications and precision material processing.

Laser beam combining merges multiple laser outputs into a single beam, achieving high power – ranging from several kilowatts to tens of kilowatts – while maintaining excellent beam quality and brightness.

Coherent Beam Combining (CBC): Extremely High Power And Extremely High Intensity

By precisely controlling the phase and frequency of multiple beams, it is possible to combine them into a single high-energy laser beam. FiberBridge Photonics offers CBC beam combiners capable of operating at total power levels of tens of kilowatts while maintaining excellent beam quality. For complete CBC laser systems, FiberBridge Photonics offers GHz seed sources, fiber-based beam splitters, phase control units, high-power narrow-linewidth fiber amplifiers and a highly efficient beam combiner unit with excellent SWaP characteristics supporting up to 127 fiber channels.

Spectral Beam Combining (SBC): Very High Power And Very High Intensity

In this approach, frequency stabilized lasers with slightly different wavelengths are combined to create a single high-power beam. FiberBridge Photonics offers SBC beam combiners, fiber amplifiers as well as complete beam combiner units with high beam quality.

Incoherent Beam Combining: Extremely High Power And Moderately High Intensity

The superimposition of independent beams allows for a comparatively simple and cost-effective approach. FiberBridge Photonics offers high-power fiber arrays, including collimation optics, capable of operating at total power levels of tens of kilowatts while maintaining excellent individual beam quality.
