Abstract :
The transient behaviour of the output of a twin stripe laser is found to be dependent upon the rise time and levels of the injection currents. Under certain biasing conditions the transient output has a high initial value which relaxes to a much lower value if the pulse rise time is fast but not if it is slower. This effect is found to be associated with beam steering.
