Plasma Optik Techne System —Qualification for High Fluence Optical Applications

Plasma Optik Techne System —Qualification for High Fluence Optical Applications

James Kraus, Senior Coating & Sales Development Engineer

Executive Summary  | Thin films exposed to high laser fluence levels benefit from having both high laser damage threshold and low absorption values. The need for high laser damage threshold is clear. Low absorption is also important due to the need to keep the optic from experiencing absorption-based heating effects while in use. Thin film stack absorption under optical load can lead to issues such as thermal lensing and premature failure of the optic. Plasma Process Group has developed the Techne Ion Beam Sputtering deposition tool designed for manufacturing these challenging coatings. Plasma Optik has optimized Techne process parameters to both maximize laser damage threshold and minimize absorption. This paper details the laser damage and absorption testing methods and these methods are discussed. Also included is laser damage and absorption performance data measured by testing of 1064nm and 532nm high reflector mirrors made with the Techne system.

Optical Coating Materials

Optical Coating Materials

James Kraus, Senior Coating & Sales Development Engineer

Executive Summary  |  A variety of materials are used in thin film optics applications. Customers of thin film optics may be interested in becoming familiar with these materials and the important differences which make one material set more appropriate for your application. We propose that the most important intrinsic material considerations are material index, material bandgap and absorption edge. These material properties are discussed as they affect thin film optics performance in different scenarios.
