Abstract: (2060 Views)
In this paper, we intend to use a Nd: YVO4 laser, whose wavelength is in the dye absorption region, to create a double-beam interference scheme on a polymer-bearing layer sample. This sample contains a dye layer of DR1, doped in PMMA polymer, in the guest-host method. Afterwards, with He-Ne laser radiation, we will see the diffraction caused by it. In the end, we will show that, by disconnecting the Nd: YVO4 laser and eliminatingthe interference pattern, the He-Ne dispersion laser effect is eliminated.
Keywords: Interference pattern, Dual-beam interference, Diffraction pattern, Absorption region, Dopped
