摘要 利用355 nm三倍频Nd∶YAG激光器为泵浦源,研究红光染料(DCJTB)在聚苯乙烯、聚甲基丙烯酸甲酯和聚N-乙烯基咔唑三种聚合物基体薄膜中放大的自发发射(ASE)特性.结果表明,DCJTB/聚N-乙烯基咔唑薄膜表现出很强的ASE,具有高增益和低阈值的特性,是一种比较优良的有机聚合物薄膜激光材料体系. This paper deals with the amplified spontaneous emission （ASE） of thin films of a red dye compound, 2-（ 1,1-dimethylethyl ）-6（2-（ 2, 3,6,7-tetrahydro-1,1,7,7-tetramethyl-1-1 H, 5H-benzo （ij） uinolizin-9-yl） ethenyl） -4H-pyran-4-ylidene） propanedinitrile （ DCJTB ）, in various polymer matrices of poly （methylmethacrylate）, poly（styrene） and poly（ N-vinyl carbazole）, which were pumped at 355 nm with THG Nd ： YAG laser. The DCJTB ： poly （ N-vinyl carbazole） film shows an effective and large ASE intensity, the lowest threshold and the maximum optical gain coefficient. Our results indicate that DCJTB ： poly （N-vinyl carbazole） could be a promising candidate for the gain medium of optically pumped polymer lasers.
