ABSTRACT
Surface-emitting polymer laser was fabricated with 1,4-bis[2-[4-[N,N-di(p-totyl)amino]phenyl]vinyl]benzene-doped poly(vinyl-pyrrolidone) thin films sandwiched between two distributed Bragg reflector (DBR) mirrors. Under pulsed optical pumping, Fabry–Perot (FP) type resonation resulted in multi-mode laser oscillations depending upon the active film thickness. With increasing excitation wavelengths, an emission peak based on stimulated resonant Raman scattering (SRRS) was superimposed on the multimode band region. When the SRRS peak just overlapped with one of the FP modes, the emission intensity was enhanced and the line width was considerably narrowed. Such SRRS-coupled FP oscillations can be applied to realize a tunable single-mode surface-emitting polymer laser.
