PQL has demonstrated the ability of HiTUS to produce very high quality optical filters and waveguide material at very high rates, while offering significant advantages over alternative technologies.  The inherent independence of HiTUS system allows accurate deposition of optical multi-layer stacks
- film properties are maintained at varied deposition rates
- dielectrics are reactively sputtered from metallic targets in most cases, leading to the densification of the deposited films
- SiO2 Ta2O5 Nb2O5 TiO2 are some of the materials we have sputtered
- Deposition is controlled by target power verses time. Expensive feedback control is not necessary.
- The process is very stable and is repeatable run to run
“PQL has deposited high quality waveguiding alumina layers that appeared to be unaffected by ultraviolet irradiation – a requirement for the “next generation” of upconversion lasers using thulium as the active laser ion.”
The HiTUS system in conjuction with PQL’s multiple target holder provides the capability to repeatedly and reliably deposit identical alternating layers of differing materials. Coupled with a menu driven PLC, one touch batch process control is easily achieved.
