Abstract

The paper discusses requirements and solutions for antireflection coatings applicable for a fused silica cell which is attended to manipulate Rydberg atoms as qubits. Multiple laser beams at various wavelengths and light incidence angles pass the different window areas of the cell. AR-coatings were designed and deposited on the window areas to receive an optimal solution for each of the lasers. Some of the coatings optimized for the internal surfaces of the cell contain nanostructured layers as an option to improve the polarization properties at higher light incidence angles. Cleaning, handling and outgassing of these layers was investigated in particular.
