FBH reports record 2kW output from single 1cm-long diode laser bar

In a talk and a tutorial at CLEO 2015 (Conference on Lasers and Electro-Optics) in San Jose, CA, USA (10-15 May), a team led by Paul Crump from FBH (Ferdinand-Braun-Institut, Leibniz-Institut fur Hoechstfrequenztechnik) of Berlin, Germany presented the latest results from the project CryoLaser (which ran from January 2012 to December 2014), demonstrating for the first time that a single 1cm laser bar can deliver at least 2kW of optical output power, when cooled to 203K.
