We have measured the electronic temperature of the upper laser level (TE u) during continuous-wave operation in THz quantum-cascade lasers and found an experimental correlation with the occurrence of stimulated emission and the internal quantum efficiency.

Abstract
We have measured the electronic temperature of the upper laser level (TE u) during continuous-wave operation in THz quantum-cascade lasers and found an experimental correlation with the occurrence of stimulated emission and the internal quantum efficiency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
