CO2 laser weapon countermeasure

Claim 1

A laser weapon countermeasure method comprising dispensing a chemical countermeasure into air of the atmosphere between that which is desired to be protected and a high power laser weapon so that said chemical countermeasure is provided along a predetermined length and of a predetermined height so as to be in the line of sight between the high power laser weapon and that which is desired to be protected, said chemical countermeasure in said atmosphere being sufficient to cause high powered laser energy radiation of 10.6 μm from said laser weapon to bloom and be dissipated and allow that desired to be protected to pass by and out of range of said high powered laser weapon, said chemical countermeasure consisting of a chemical selected from the group consistings of 1,1-difluoroethylene, dichlorodifluoromethane, perfluoro-2-butene, octafluorocyclobutane, chloropentafluoroethane, 1,2-dichlorotetrafluoroethane, 1,1-difluoro-1-chlorethane, 1,1-difluoroethane, 3-methyl-1-butene, ethylene, propylene, and dimethyl ether, and said chemical countermeasure being dispensed in an amount of about 2 to about 10 pounds over a length of about 1 km.
