Advancements in the Optical Damage Resistance of Ion Beam Sputter Deposited Interference Coatings for High Energy Lasers
MetadataShow full item record
The work presented in this thesis is dedicated toward investigating, and ultimately improving the laser damage resistance of ion beam sputtered interference coatings. Not only are interference coatings a key component of the modern day laser, but they also limit energy output due to their susceptibility to laser induced damage. Thus, advancements in the fluence handling capabilities of interference coatings will enable increased energy output of high energy laser systems. Design strategies aimed at improving the laser damage resistance of Ta₂O₅/SiO₂ high reflectors for operation at one micron ...
