Abstract
Systems and methods for oxide-based doping of an evaporable getter are described herein. In certain embodiments, a method includes mixing a first getter material with a second getter material to create a mixed getter material. The method also includes mixing an oxide dopant with the mixed getter material to create a doped getter material. Further, the method includes sealing the doped getter material within a device. Moreover, the method includes applying heat to the doped getter material to cause the doped getter material to emit a doped gas for deposition on internal surfaces of the device.

A method comprising:
- mixing a first getter material with a second getter material to create a mixed evaporable getter material;
- mixing an oxide dopant with the mixed getter material to create a doped evaporable getter material;
- sealing the doped evaporable getter material within a device;
- and
- applying heat to the doped evaporable getter material to cause the doped evaporable getter material to emit a doped gas for deposition on internal surfaces of the device.
A device comprising:
- a housing;
- a cavity within the housing;
- a getter cavity adjacent to the cavity within the housing, wherein gas passes between the cavity and the getter cavity, and the cavity and the getter cavity are sealed within the housing from an external environment of the housing;
- and
- a getter holder located within the getter cavity configured to hold a doped evaporable getter material, wherein the doped evaporable getter material comprises a mixture of:
- a first getter material;
- a second getter material;
- and
- an oxide dopant.
A ring laser gyroscope comprising:
- a housing;
- a cavity within the housing;
- a plurality of electrodes for generating counter-propagating lasers within the cavity;
- a plurality of mirrors mounted within the cavity to direct the counter-propagating lasers through the cavity;
- and
- a deposited getter film on an interior surface of the cavity that is a result of a chemical reaction of a doped evaporable getter material that comprises a mixture of:
- a first getter material;
- a second getter material;
- and
- an oxide dopant.
