Compact laser system for directed energy applications

A method for disabling or destroying an unmanned aerial vehicle (UAV), comprising:

• generating, by a plurality of laser devices of an anti-UAV system, a plurality of laser beams at a plurality of different wavelengths;
• combining, by the anti-UAV system and using a coarse wavelength division multiplexing (CWDM) combiner, the plurality of laser beams from the plurality of laser devices into a combined laser beam;
• and
• based on detecting the UAV, directing, by the anti-UAV system, the combined laser beam from the CWDM combiner onto the detected UAV.

An anti-unmanned aerial vehicle (UAV) computing platform, comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed by the one or more processors, facilitate:
• providing instructions to output a combined laser beam at a first scan angle, wherein a coarse wavelength division multiplexing (CWDM) combiner combines a plurality of laser beams that are at a plurality of different wavelengths into the combined laser beam;
• detecting an unmanned aerial vehicle (UAV) within the first scan angle of the combined laser beam based on a reflection of the combined laser beam;
• and
• based on detecting the UAV, providing instructions to the CWDM combiner to converge the combined laser beam onto the detected UAV by reducing the first scan angle.
