Paper Abstract

A compact, low-cost semiconductor laser diode producing 40 ps full width at half maximum (FWHM) single-spike lasing pulses with 6 Watts peak power from a 20 μm stripe width is realized in the form of a simple single-heterostructure, grown by metal-organic chemical vapor deposition. The structure possesses a linearly graded doping profile extending from the p+ and n+ sides towards the p-n junction. This laser diode is operated under room temperature conditions and applies pumping current pulses (roughly 10 to 20  A/2 to 3 ns FWHM) achievable with a commercially available silicon avalanche transistor as an electrical switch.
