摘要：

We report on the laser modes in optically pumped solid-state lasers using an electroluminescent organic semiconductor as the active medium. Mechanically flexible distributed-feedback lasers are fabricated by depositing a thin film of an active material onto a nano-patterned polyester substrate either via spin-coating of a soluble ladder-type poly(p-phenylene) or via vacuum co-sublimation of small organic molecules. The different surface texture resulting from the fabrication process causes different feedback mechanisms. In both lasers higher lateral modes give rise to a broadening of the laser spectra at higher pumping levels.
