| 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650nm, 观察到了明显的激光现象, 其中阈值强度约为110W·cm-2, 阈值前后的FWHM从4.7nm窄化到3.2nm。

| Abstract: | Organic microcavity structures were designed and fabricated with distributed Bragg reflector 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 microcavity 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 110W·cm-2. FWHM was narrowed from 4.7 to 3.2nm before and after the threshold. |
