Abstract

In order to develop optical coating devices for high power laser systems, it is necessary to have coatings with ultra low absorption loss, high laser damage threshold and good mechanical adhersion properties. Ion assisted deposition (IAD) is known to produce thin films with characteristics that the conventional thermal evaporation techniques can not realise[1], and meets the needs of this.
