Localised Temperature Dynamics of Gaaias Laser Facets Investigated by Raman Microprobe Measurements

Abstract

Raman micro-probe studies of diode laser facet temperatures in CW operation show a significant linear temperature rise below the laser threshold and a rapid nonlinear heating above the threshold. Dynamical measurements using current injection pulses show fast heating of the laser facet with a sub-microsecond risetime and much slower cooling within several micro-seconds. © 1990, The Institution of Electrical Engineers.
