An improved singlet delta oxygen generator (SOG) and method of its use are disclosed. The improved SOG is compact and scalable, capable of operating in a zero-gravity or low gravity environment, requires no gaseous diluent or buffer gas, and is capable of operating at pressures as high as one atmosphere. The improved SOG also efficiently utilizes the reactants and produces a O2(1Δ) stream that is largely free of chlorine and water vapor contamination and therefore does not require a BHP regeneration system or a water vapor trap. When used as part of a COIL system, the SOG may be part of a plenum that directly feeds the laser's nozzle. The close proximity of the SOG to the laser cavity allows operation of the SOG at higher pressures without significant depletion of available O2(1Δ) through collisional deactivation.

The invention claimed is: 1. A singlet delta oxygen generator (SOG), comprising: a generator for producing froth from at least a reaction of a basic hydrogen peroxide (BHP) solution and chlorine having a porous inlet for the chlorine; and a chamber for receiving the froth, wherein the chamber includes a throat for carrying singlet delta oxygen produced by the froth. 2. The SOG of claim 1, wherein the generator further comprises: a BHP inlet; and a ramp that receives the BHP solution from the BHP inlet, wherein the ramp includes a converging section and a diverging section. 3. The SOG of claim 2, wherein the porous inlet is located in the diverging section of the ramp. 4. The SOG of claim 1, wherein the throat feeds a laser cavity of a Chemical Oxygen Iodine Laser (COIL). 5. The SOG of claim 4, wherein the chamber further comprises: a curved wall section in fluid communication with the generator at a first end for carrying the froth from the generator; a Converging-Diverging (CD) nozzle which includes the throat that is in fluid communication with the froth along the curved wall section; and an exhaust in fluid communication with the curved wall section at a second end for carrying away spent reactants. 6. The SOG of claim 1, wherein the pressure in the generator is between about 100 Torr to about 760 Torr. 7. The SOG of claim 1, wherein the SOG further comprises a cooling system for cooling the BHP solution to a temperature between about 5�� C. and about 10�� C. above its freezing point prior to the BHP inlet. 8. The SOG of claim 1, wherein the chlorine molar flow rate is about 70-120% of the molar flow rate of the BHP solution. 9. A COIL, comprising: a SOG having: a generator for producing froth from at least a reaction of a BHP solution and chlorine having a porous inlet for the chlorine; and a chamber for receiving the froth, wherein the chamber includes a throat for carrying singlet delta oxygen produced by the froth; and a laser cavity for receiving singlet delta oxygen from the throat. 10. The COIL of claim 9, wherein the generator further comprises: a BHP inlet; and a CD nozzle which receives the BHP solution from the BHP inlet. 11. The COIL of claim 10, wherein the porous inlet is located in the diverging section of the CD nozzle. 12. The COIL of claim 9, wherein the chamber further comprises: a curved wall section in fluid communication with the generator at a first end for carrying the froth from the generator; a CD nozzle which includes the throat that is in fluid communication with the froth along the curved wall section; and an exhaust in fluid communication with the curved wall section at a second end for carrying away spent reactants. 13. The COIL of claim 7, wherein the pressure in the SOG is between about 100 Torr to about 760 Torr. 14. The COIL of claim 7, wherein the SOG further comprises a cooling system for cooling the BHP solution to a temperature between about 5�� C. and about 10�� C. above its freezing point prior to the BHP inlet. 15. The COIL of claim 7, wherein the chlorine molar flow rate is about 70-120% of the molar flow rate of the BHP solution. 16. A singlet delta oxygen generator (SOG), comprising: a generator for producing froth from at least a reaction of a BHP solution and chlorine having a porous inlet for the chlorine, wherein the generator includes: a BHP inlet; and a ramp that receives the BHP solution from the BHP inlet, wherein the ramp includes a converging section and a diverging section; and a chamber for receiving the froth, wherein the chamber includes a throat for carrying singlet delta oxygen produced by the froth. 17. The SOG of claim 16, wherein the porous inlet is located in the diverging section of the ramp. 18. The SOG of claim 16, wherein the throat feeds a laser cavity of a Chemical Oxygen Iodine Laser (COIL). 19. The SOG of claim 1, wherein the SOG further comprises a cooling system for cooling the BHP solution to a temperature between about 5�� C. and about 10�� C. above its freezing point prior to the BHP inlet. 20. The SOG of claim 1, wherein the chlorine molar flow rate is about 70-120% of the molar flow rate of the BHP solution.
