ALPHA-RLH (Route des Lasers & des Hyperfréquences) is a newly formed technology cluster specializing in photonics, lasers, microwave and digital technologies. It is the result of a merger between two French competitiveness clusters, Route des Lasers and Elopsys.

Scientists at ANU have improved the performance of tiny lasers by adding impurities, in a discovery which will be central to the development of low-cost biomedical sensors, quantum computing, and a faster internet.

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams.
