Researchers at a US lab have passed a crucial milestone on the way to their ultimate goal of achieving self-sustaining nuclear fusion.

A hand-held laser for use in the dismantling of metallic infrastructures during the decommissioning of nuclear facilities has been developed by the UK's TWI.

Normal laser stimulates emission of radiation by the transfer of electrons being in the working chamber to the excited state, and when they reach a high enough energy, they can give up a part of it by emitting photons. It was they who form a coherent beam of light that we call laser radiation.

ADAM is a mobile laser HEL system mounted on a car trailer. The relatively small size and weight of the system allows to bring and deploy it quickly at the right place.

The research team from the Heriot-Watt University in Edinburgh, Scotland, led by Gerald Buller, has developed a new system consisting of a camera and a laser that can create a three-dimensional image with a relatively high resolution from a distance of up to one kilometer.
