Ceramic Cavity Low Drift

Standard cavity filters generally are designed using aluminum as the base metal.

Ceramic cavity low drift.

We describe a cw laser stabilized to a low thermal expansion ceramic cavity which has a lower frequency drift rate than cavities based on ultralow expansion glass ule which are widely used as optical references.

The filters based on cavity resonators have the advantages of low insertion loss and high power handling capability compared to the filters based on lumped element lc satellite applications 1. We describe a cw laser stabilized to a low thermal expansion ceramic cavity which has a lower frequency drift rate than cavities based on ultralow expansion glass ule which are widely used as. Ceramic cores are sacrificial ceramic structures primarily used for forming cavities that are too small or complex to be machined within investing casting procedures. Filter housings are silver plated for improved electrical characteristics and current flow.
