Effect of Laser Pulse Energy and Repetition Rate on Optical Transmittance Spectra of Fe2O3Thin Films

Abstract

In this work; iron oxide thin films (Fe2O3) were fabricated by pulsed laser deposition technique (PLD). Pulsed Nd: YAG laser was used for prepared Fe2O3 thin films at wave length 532nm and 10 ns pulse duration with varying both pulse energy and laser repetition rate. The optical transmittance spectrum of Fe2O3 thin films was measured experimentally and the effects of laser pulse energy and laser repetition rate on it were studied. An inverse relationship between transmittance spectra and both laser pulse energy and laser repetition rate was observed
