An organic laser diode model:a comparison between numerical and experimental dynamical responses in the high-current density nanosecond pulse regime below threshold
Recently, Adachi and co-workers have reported convincing proof of stimulated emission in an organic hetero-structure under electrical excitation [1]. This new organic laser diode opens a new era in the field of\u3cbr/\u3elasing with solid-state organic materials that covers the whole visible spectrum and can be patterned more easily than conventional III-V materials. This new device combines properties from dye-lasers and diode laser, and thus will also open new research in the field of laser dynamics with promising new and interesting behavior.\u3cbr/\u3eIn this study we propose a first organic laser diode model, and we check its validity by comparing the numerical results with experimental measurements acquired in the nanosecond pulsed regime below threshold. For the first time, we identify one parameters of the model that has been underestimated
