Keywords:organic semiconductor, laser, field-effect transistor

Light amplification in an organic semiconductor was realized for the first time by injecting high-density electron and hole current into an ambipolar organic single-crystalline FET. Comparison of electrically-excited and optically-excited amplified light will be discussed in the presentation.
