Organic solid laser pumped by an organic light-emitting diode.

We have proposed what we believe is a novel organic device pumped by an organic light-emitting diode to avoid a strong charge-induced absorption and nonradiative loss in an electrically pumped organic laser. An organic light-emitting diode was fabricated on the transparent anode substrate with a microcavity structure and driven under intense pulse voltages, and an organic film with a low threshold of amplified spontaneous emission was spin-coated on the opposite side of the substrate. Edge emission, spectral from the film, has been measured under the pulse voltages. The optical characteristics of organic films under an Nd3+: YAG laser have also been studied.
