Abstract
We report on measurements of laser emission from poly-methylmethacrylate an
d poly-vinyl carbazole polymer films doped with rhodamine-6G, DCM and couma
rin laser dyes in an optically pumped distributed feedback scheme. We obtai
n tunability on a broad spectral range for all samples. We show the impact
of waveguiding in the polymer film on reducing the laser threshold. We also
show that the number of laser modes increases with the polymer film thickn
ess, following the guided mode dispersion.
