Fully organic nanofiber lasers, made by a polymer matrix doped with gain molecules, are demonstrated. They exhibit emission in the visible and near infrared range (see image), supporting efficient waveguiding of the self‐emitted light. Individual fibers can operate as optical cavities, emitting single‐mode laser light at visible wavelengths with a threshold of tens of µJ cm −2 .
