Abstract
Laser action at 420 nm is observed in photopumped polymer films of
polystyrene (PS) doped with the hole-transporting organic molecule
N,N′-bis(3-methylphenyl)-N,N′-dyphenylbenzidine (TPD). Measurements of
the dependence of signal on the length of the pump stripe show that
the mechanism responsible for the observed spectral collapse is
amplified spontaneous emission (ASE). By fitting the evolution of the
output intensity at 420 nm with the excitation length, gain
coefficients up to 16 cm-1 are measured.
