摘要/Abstract

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.

Abstract: 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-1-1H,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.

Key words: DCJTB, polymer film, amplified spontaneous emission
