Scientists have created a laser-based charging system that sends power through a focused beam. This allows devices, including drones, to charge from a distance while staying in the air.

The system is developed by Power Light Technologies. It uses a ground-based power transmitter and a special receiver installed on the drone. The receiver converts the laser beam directly into battery power.

According to researchers, the laser beam can deliver thousands of watts of energy. The power transmitter can work from distances of up to 1,500 meters, making long-range charging possible.

Advanced software helps the transmitter lock onto cooperative targets. It can track a drone’s movement and keep the laser aimed at the receiver even while the drone is flying.

An integrated control system allows operators on the ground to monitor battery levels in real time. This helps them manage power supply and make quick decisions during flight.

Experts say the technology could be a breakthrough for military drones. With laser charging, drones could stay airborne for very long periods and strike multiple targets without returning for recharging.

PowerLight’s Chief Technology Officer and Co-Founder, Tom Nugent, said, “We are building an intelligent mesh energy network capability. Our transmitter communicates with the UAS, tracks its volatility, and delivers energy exactly where it’s needed.”
