Abstract
Mirrorless laser action has been observed in thin films of a π-conjugated polymer. The many mode emission spectrum from a stripe excitation geometry suggests true las-ing. Analytical tools developed for microring polymer lasers are applied to the laser emission spectra of films to determine the dominant resonator lengths. Using the coherent backscattering technique the light mean free path, It is determined to be 15μm. With the obtained resonator loops of 155μm, the dominant laser cavity consists of ∼ 10 scatterers.
