中文摘要：

设计研制了以分布式布拉格反射镜为腔镜、以主客体掺杂的红光发光材料Alq∶DCJTI为增益介质的有机微腔结构。通过传输矩阵法对腔内驻波光场进行了模拟,确定了合理的微腔结构。在紫外脉冲激光的泵浦下研究了微腔的激光性能。该微腔激光器的输出波长位于650 nm,观察到了明显的激光现象,其中阈值强度约为110 W·cm-2,阈值前后的FWHM从4.7 nm窄化到3.2 nm。

英文摘要：

Organic microcavity structures were designed and fabricated with distributed Bragg reflec-tor as the mirror and Alq∶DCJTI host-guest doping system as the gain medium. The standing wave field within microcavity was simulated by using the transfer matrix method, and a suitable microcavi-ty structure was determined. The lasing properties of the microcavity laser were studied by a UV pulse laser. The output wavelength of the microcavity laser is 650 nm. An obvious lasing behavior was observed with a threshold intensity of 110 W·cm-2 . FWHM was narrowed from 4. 7 to 3. 2 nm before and after the threshold.
