摘要:
We present results of pump‐probe experiments on GaAlAs laser diodes indicating a 0.9‐ps relaxation time associated with the device transmission. Subpicosecond, tunable near infrared pulses obtained by fiber compression were used to carry out the experiments. The data strongly support a model in which a nonequilibrium carrier temperature in the active layer is responsible for the observed signal.
