Paper Abstract

We study the output of a gain switched diode laser as a function of the pumping parameters. Experimentally we look at the output pulse shape height and width timing conditions and stability. Theoretically we calculate the conditions under which a gain switched diode laser is optimized with respect to the width of the injection current pump pulse. We find for both biased and unbiased operations that a current pulse of approximately 20 psec corresponds to a Dirac delta function a situation which yields the shortest most intense output pulses. A sensitivity analysis performed on an analytic distillation of the model gives us design considerations for diode lasers with improved stability.
