Ground-based counterspace systems using high-energy lasers are becoming increasingly important in modern defense and space security. Military and commercial infrastructures rely heavily on satellites for communication, navigation, reconnaissance and surveillance, which means the ability to disrupt or disable space-based assets has major strategic relevance.

Counterspace applications require extremely high optical power levels due to atmospheric losses, beam spreading and the long distances involved. Depending on the target and operational range, laser systems may require output powers from several tens of kilowatts up to multi-hundred-kilowatt or even megawatt-class levels. Achieving both high power and excellent beam quality simultaneously remains one of the main technological challenges.

Coherent beam combining (CBC) is considered a key enabling technology for future high-energy laser systems. Rather than relying on a single extremely powerful laser source, CBC combines multiple fiber lasers into one coherent beam with significantly higher total power. This approach offers several important advantages: Fiber lasers provide excellent electrical efficiency, thermal management, scalability and reliability compared to traditional bulk laser architectures.

CBC also addresses critical limitations of single-aperture laser systems. As laser power increases, thermal effects, nonlinearities and beam distortions can significantly reduce beam quality and targeting precision. By coherently combining many smaller laser channels with active phase control, CBC systems can maintain high beam quality while scaling to much higher power levels. In addition, modular laser architectures simplify maintenance, improve redundancy and allow flexible system expansion.

Another major challenge for ground-based laser systems is atmospheric turbulence. Variations in air density and temperature distort the laser beam during propagation. CBC architectures can partially compensate for these effects.

FiberBridge Photonics CBC high-energy laser systems provide a solution for these high-intensity applications. CBC systems coherently combine multiple laser channels into a single high-brightness output beam while maintaining excellent beam quality. This allows the laser power to be scaled far beyond 100 kW while still maintaining excellent beam quality (M² ~ 1).
