Notes:
Laser radiation from GaAs/AlGaAs laser diode arrays of high output power is studied during nano- to millisecond carrier injection in temporally and spectrally resolved emission measurements. A red shift of the multimode emission spectrum by up to 12 nm and a concomitant increase of the total bandwidth are caused by a transient rise of the device temperature by up to 50 K. Spatially resolved experiments reveal a lateral temperature difference of about 2 K between the center and the edge emitters. Different laser array/heat sink combinations are investigated in order to reduce the transient temperature increase. © 1996 American Institute of Physics.
