摘要: 采用新型有机吡啶盐trans-4-［p-（N-hydroxyethyl-N-methylamino）styryl］-N-methylpyridinium iodide （ASPI）与有机小分子８-羟基喹啉铝（Alq3）组成能量传递体系，掺杂于惰性聚合物聚甲基丙烯酸脂（PMMA）薄膜中作为增益介质，利用分布布拉格反射镜（DBR）和金属Ag层作为反射镜，制备了垂直微腔结构的有机半导体固体激光器.在纳秒脉冲激光抽运下研究了该有机微腔的受激发射特性，观测到峰值位于600 nm处谱半高全宽为243 nm的单模激光出射;同时观察到明显的激光能量阈值特性，单脉冲的受激发射能量阈值为8?J.-----------------2009年《物理学报》第58卷第4期第2781-2784页一文，由于作者的责任，故撤销该文。
Abstract: An organic vertical cavity surface emitting laser has been fabricated, using a Forster energy transfer system of organic pyridium salt dye ASPI and Alq3 doped in PMMA film as the gain medium, which was sandwiched between a high-reflectance distributed Bragg reflector and a silver reflector. The stimulated emission properties were investigated by nanosecond-pulsed laser pumping. The lasing phenomenon was observed with a full width at half maximum of 243 nm at the lasing wavelength of 600 nm, and the threshold energy for lasing was estimated to be about 8?J per pulse.
