Abstract

A system for chemical and biological decontamination has a source of oxygen. A reactor is coupled to the source oxygen. An optical source is coupled to the reactor. The system produces singlet delta oxygen that neutralizes chemical and biological contaminants.

Claims (26)

1. A reactor, comprising:

an inlet;

a first pair of mirrors, one of the first pair of mirrors adjacent to the inlet and a second of the first pair of mirrors adjacent to an outlet; and

a second pair of mirrors having an optical axis perpendicular to an optical axis of the first pair of mirrors.

2. The reactor of claim 1 , wherein the first pair of mirrors are circular mirrors.

3. The reactor of claim 2 , wherein the second pair of mirrors are concentric with the first pair of mirrors.

4. The reactor of claim 3 , wherein the first pair of mirrors and the second pair of mirrors are confocal.

5. The reactor of claim 3 , wherein the second pair of mirrors form a partial cylinder.

6. The reactor of claim 5 , wherein an end of the partial cylinder is an inlet for a plurality of pump photons.

7. The reactor of claim 6 , further including a second outlet near the outlet adjacent to the second of the first pair of mirrors.

8. The reactor of claim 7 , wherein a nitrogen gas exits the second outlet.

9. A reactor, comprising:

a surface coated with a photosensitizer; and

an optical source directing light at the surface, wherein the surface is transparent to the light of the optical surface.

10. The reactor of claim 9 , wherein the photosensitizer is organic photosensitizer.

11. The reactor of claim 10 , wherein the organic photosensitizer is a red photon absorbing material.

12. The reactor of claim 11 , wherein the surface is a tube with a plurality of micro-channels.

13. The reactor of claim 9 , wherein the surface is optical quality glass.

14. The reactor of claim 9 , wherein the optical source is a plurality of laser diodes.

15. A reactor, comprising:

an optical source having an optical output;

a chamber having an inlet for the optical output; and

a gas flowing through the chamber.

16. The reactor of claim 15 , wherein the chamber has a tube with a plurality of micro-channels, the micro-channels coated with an organic photosensitizer.

17. The reactor of claim 15 , wherein the chamber has a first pair of mirrors and a second pair of mirrors that is concentric with the first pair of mirrors.

18. The reactor of claim 17 , wherein the first pair of mirrors are confocal with the second pair of mirrors.
