Engineered for the deuterium fluoride working environment of DF chemical lasers, we provide precision machining and surface fluorination/passivation of specialty structural components such as optical resonators and nozzles, controlling critical mating surfaces and flow channels to high-vacuum standards. Cavities and gas supply manifolds undergo leak testing and pressure-hold verification to meet high-vacuum airtightness criteria for resonators and nozzles, while D₂, F₂, and He media are accurately proportioned and fed by multi-channel high-purity gas supply units. Post-reaction fluorine- and deuterium-containing exhaust passes into high-temperature neutralization and adsorption modules, paired with on-site scrubbing procedures for safe discharge.
