Abstract :
The first vertical external cavity surface emitting lasers (VECSELs) that have a continuous-wave power output over 100 W, even up to 3 C, have been reported in joint work from Philipps-Universita t Marburg in Germany and the University of Arizona in the US. Key changes to the design, growth procedure, chip mounting and thermal management allowed the researchers to reach 106 W at 1028 nm, which is over 30 W higher than their previous record set at 15 C.
