ABSTRACT
Single-mode tunable laser emission is obtained from a stable cavity based on a prototype compound of a class of functionalized electroluminescent oligothiophenes. Laser emission is demonstrated in the red spectral region with a tunability wavelength range of 30 nm, centered at 607 nm. The laser exhibits a well-defined pump threshold and good emission characteristics. The results suggest the use of the family of functionalized oligothiophenes as optical amplifiers covering the whole visible spectral region. © 2001 American Institute of Physics.
