Pentacene is the key material in organic semiconductor technology. The existence of nano-structured thin film was confirmed by atomic force microscopy and X-ray diffraction. The wavelength-dependent transmittance and reflectance were calculated to observe the optical behavior of the pentacene thin film. It has been observed the anomalous dispersion at wavelength lambda < 800 nm, whereas the normal dispersion was found at wavelength lambda > 800. The non-linear refractive index of the deposited films was investigated. The linear optical susceptibility of pentacene thin film was calculated, and we observed the non-linear optical susceptibility of pentacene thin film at about 6 x 10(-13) esu. The advantage of this work is to use of spectroscopic method to calculate the liner and non-liner optical response of pentacene thin films rather than expensive Z-scan. The calculated optical behavior of the pentacene thin films could be used in the organic thin films base advanced optoelectronic devices such as telecommunications devices  ISSN : 0946-2171  Journal Name : APPLIED PHYSICS B-LASERS AND OPTICS  Volume : 122  Issue Number : 7-8  Publishing Year : 1437 AH 2016 AD  Article Type : Article  Added Date : Wednesday, August 9, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email I.S Yahia, Yahia,, I.S Investigator Doctorate   S Alfaify Alfaify, S Researcher Doctorate   Asim) Jilani, Jilani,, Asim) Researcher Doctorate asim.jilane@gmail.com M.
