دراسة تأثير السمك على الخصائص البصرية للوسط الليزري اللدائني الفعال

الملخص EN

The paper include study the effect thickness of the polymeric sample which is manufactured by thermo press way.

The sample was used as an active tunable R6G laser media.

The remarks show that, when the thickness of the samples is increased, with the same concentration, the spectrum will shift towards the short wavelength, & the quantum fluorescence yield will increased.

The best result we obtained for the quantum fluorescence yield is (0.68) at the sample, with thickness (0.304mm) in Ethanol solvent, while when we used the Pure Water as a solvent, we found that the best quantum fluorescence yield is (0.63) at (0.18mm) thickness of the sample.
