Optical trains exploited in the various applications using the high power continuous wave lasers suffer severely from the damages due to the extremely high and non-homogeneous energy density distribution. In present project, the possibility of exploiting novel Transition metal oxide functionalized materials and meta-structures to mitigate the breakdown phenomena in these components will be investigated. The coatings will be fabricated via pulsed laser deposition and will be investigated for their relative physico-chemical properties to understand the mitigation mechanisms and optimise the required optical properties.
