Abstract :
There is currently considerable experimental research regarding the use of organic materials in the construction of laser diodes. Problems with electrically pumping organic semiconductor lasers (OSL) arise from the comparatively poor internal quantum efficiency of the material, resulting in much lower levels of material gain under electrical excitation than for optical pumping schemes. It is therefore desirable to reduce the pumping thresholds of organic lasers as much as possible
