Abstract: Methods, systems, and devices are described. A system may include an optically transmissive substrate having a protective coating on a first surface and a blocking coating on a second surface that is opposite the first surface. The protective coating is configured to protect the optically transmissive substrate from at least ultraviolet laser energy, and the blocking coating has a first thickness that is less than about 280 nanometers and is adhered to a subset of the second surface. The system further includes a capping layer covering the blocking coating that is on the subset of the second surface and having a second thickness less than the first thickness of the blocking coating. Additionally, the system includes a sealing component positioned between the capping layer and a structure configured to support the optically transmissive substrate.
