A defence fair in Beijing has shown portable laser weapons that can be carried by a single soldier to shoot down drones, realising a vision that was once the domain of science fiction.
The Lijian series, meaning “sharp swords”, developed by Chinese defence supplier Harbin Xinguang Optic-Electronics Technology, was displayed at the Defence Information Equipment & Technology Exhibition 2026, a three-day event that started in Beijing on Tuesday.
The Lijian series uses high-energy lasers to shoot down drones at ranges up to 1,200 metres (3,900 feet), although the portable models have a much shorter range, according to information posted at the exhibition.

Laser weapons are considered effective for fighting drones as they can burn unmanned aerial vehicles (UAVs) in the air at a relatively low cost, compared with shooting them down with bullets or artillery.
The Lijian series has taken the concept a step further by reducing the weight of its weapons, presenting portable systems alongside those for installation on vehicles and fixed sites.
The portable systems, the Lijian II and Lijian III, have just three main components: a laser emitter, an air cooler and a handheld control terminal.
These components can be stored and carried in a bag. The Lijian II weighs 30kg (66lbs), and the Lijian III weighs 25kg.
