DECONTAMINATION APPARATUS AND METHOD

摘要

A decontamination apparatus 200A and method of fluid decontamination comprises a laser having an optical resonance cavity disposed between a first reflector 221 and a second reflector 221 and passing a fluid for decontamination through the optical resonance cavity. The fluid may flow though an enclosed channel 230 transparent at the laser frequency and the laser generates UV light 212 for decontamination purposes. An energy pump (240, fig 7) such as a flash lamp, laser diode, electrical discharge or RF or microwave energy source may be used for stimulation of the laser and the fluid may be passed through a region of generated output of the energy pump (240). The optical resonance cavity may comprise a beam expanding telescope (215, fig 9) or a prism (217, fig 10) forming a light sheet. The fluid may be air and nitrogen in the air may act as a gain medium 210 of the resonance cavity (fig 8). The fluid may be passed through an electric field generator (figs 13 — 14B & 16) comprising electrodes (340) with a roughened surface profile (342). The electrodes (440A, 440B figs 17A & 17B) may be rotatable and the electric field generates plasma discharges.
