摘要

利用飞秒脉冲研究了罗丹明6G在乙醇和PMMA中的双光子吸收特性。罗丹明6G在PMMA中的双光子吸收截面比在乙醇中的大得多。研究了该染料在乙醇和PMMA中的荧光特性。在800 nm激发下,罗丹明6G在PMMA溶液中的双光子吸收失谐比在乙醇溶液中的失谐减小。罗丹明6G在PMMA中双光子吸收截面的增大主要是由于失谐的减小。

Two-photon absorption properties of rhodamine 6G in ethanol and PMMA
Two-photon absorption properties of rhodamine 6G in ethanol and PMMA were researched applying femtosecond pulses. The two-photon absorption cross section of rhodamine 6G in PMMA was found much larger than that in ethanol. Fluorescence properties of this kind of dye in ethanol and PMMA were also researched. The detuning of two-photon absorption for rhodamine 6G dissolved in PMMA is diminished compared with that in ethanol when excited at 800 nm. And the increase of two-photon absorption cross section of rhodamine 6G in PMMA was attributed mainly to the diminishing of detuning.
