Under pulsed operation, time dependent spectral and electro‐optical measurements on GaN‐based laser diodes show a considerable red shift in the emission wavelength and a decreasing voltage drop across the device. These changes appear on a rather short time scale in the microsecond range. During a 3.7 microsecond long pulse, a temperature increase of approximately 50 K is obtained using different experimental methods. This value agrees well with numerical simulations based on the thermal properties of the material. (© 2003 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
