Wisconsin-based diode laser company Alfalight has been awarded an 18-month, $4.7 million US Defense Advanced Research Projects Agency (DARPA) contract to develop a 50W single-emitter laser diode.
The research is part of DARPA’s Architecture for Diode High-Energy Laser Systems programme. Its goal is to produce a multi-kilowatt diode laser system. Single emitters of less than a kilowatt of power would be combined to produce a multi-kilowatt beam.
In January 2006 Alfalight demonstrated a prototype 22W diode laser.
