摘要
The stimulated emission properties associated with high optical gain is investigated in pure methyl-substituted poly-(paraphenylene) laddertype polymer (m-LPPP). Amplified spontaneous emission (ASE) in combination with waveguiding in the polymer film results in a highly directional linear polarised blue output at low pumping threshold of 3kW/cm(2). Above a threshold value of 400 kW/cm(2), additional narrow lines can be observed, that are assigned to amplified Stokes modes of stimulated Raman scattering (SRS). The output characteristics of different waveguides are investigated and explained by leaky wave propagation.
