One of the most important factors for increasing laser efficiency is the quality of optical elements which are used in laser systems. The quality of these elements is dependent on various parameters such as spectrum of laser light, adhesion and damage threshold. Anti reflective coatings have many applications in optics, for instance lasers, lenses and solar cells. In this study, we have been investigated design and fabrication of anti reflective filter for the visible and near-infrared regions of Nd:YAG laser.
