Pulsed L-I characteristics of 670nm AlGainP/InGaP broad area lasers

摘要

We report the results of the pulsed L-I characteristics of 670 nm AlGaInP/InGaP broad area lasers. The measured pulsed L-I curves are found to be strongly dependent on the duty cycles of the applied current pulses, which were mainly attributed to the heating effect within the AlGaInP/InGaP lasers. Current pulse heating effects are negligible only at pulse duty cycles Of 0.036/100 or below.
