Power laser sources are becoming increasingly vital in defence and space applications due to their unique capabilities and versatility. In defence, these lasers offer precise and effective solutions for targeting and neutralizing threats such as missiles, drones, and other airborne objects. Laser systems can disrupt enemy communications and electronic systems, providing tactical advantages on the battlefield. Moreover, in space applications, high-power lasers have the potential to revolutionize satellite protection, space debris removal, and propulsion systems, opening new frontiers for exploration and defence.
