The Laser Weapon System or LaWS is a directed-energy weapon being developed by the U.S. Navy.
The AN/SEQ-3 Laser Weapon System or XN-1 LaWS is a directed-energy weapon developed by the United States Navy. LaWS uses an infrared beam from a solid-state laser array which can be tuned to high output to destroy the target or low output to warn or cripple the sensors of a target.
