Lasing Behavior of BMPPV:PVK Mixture in Microcavity
Lasing Behavior of BMPPV:PVK Mixture in Microcavity
摘要
Abstract
The surface emitting microcavity is formed by sandwiching a polymer film containing poly(para-phenylene vinylene)(BMPPV) and poly(N-vinylcarbazole)(PVK) between a DBR with a reflectivity of 99.5% and a silver film. The sample is optically pumped by a 337.1 nm line of nitrogen laser with 10 ns pulses at 20 Hz repetition rate . The lasing phenomenon is observed in BMPPV and PVK mixture microcavity. The full width at half maximum (FWHM) is 6 nm at the peak wavelength of 460 nm. The lasing threshold energy is estimated to be about 5 μJ.
