Do we believe that one day electrically pumped organic lasers can be realised since so much fundamental and publications were done for this purpose?
Yes, Electrically pumped organic lasers are now reality with lot of literature available.
Dear Virendra,
Thanks for your reply.
I know some literatures or research groups who claimed that they produced electrically pumped organic lasers. In reality it is not true. As far as i am aware that it was spectral narrowing due to microcavity used. The emission is not laser at all.
If you know any literatures or research groups recently published and claimed that they realised electrically pumped organic lasers, could you please let us know. Very much appreciated.
Best regards

Dear Rafid,
I am fully aware of that publication and know the group. Even one research group from Japan recently published a paper claimed that they realised the electrically pumped orgaic laser using grating structures within the cavity. Again, we went through the paper. Both cases adopted very high pulsed driven mode with extremely high current density and power. The spectra are not narrow enough. They didn't use spectral mode structure concepts to prove that it is lasing. Both results are spectral narrowing or ASE.
Please see the paper published in Nature Photonics volume3, pages546–549 (2009).
