In the majority of solid state YAG laser systems gold plated elliptical and close-coupled pump cavities are the preferred reflector used. Most optical pump cavities are typically produced from metals such as Aluminium, Stainless Steel, and Bronze. After machining the reflective surfaces are mechanically polished to mirror finish and depending on the base metal used a combination of under-plating is applied prior to the final gold plating process.
We provide a comprehensive range of retrofit and bespoke pump cavities. If you require a custom produced cavity, please provide us with an original sample or an engineering drawing.
