ABSTRACT:
An iodine chemical laser is disclosed comprising: a laser cavity; a combustion chamber; a first injector injecting into said combustion chamber an iodine compound as a fuel; a first supply means for supplying the fuel to said first injector; a second injector for injecting F.sub.2 and NF.sub.3 into said combustion chamber; a second supply means for supplying said F.sub.2 and NF.sub.3 to said second injector; combustion initiating means for initiating combustion of the mixture fuel-combustion supporter in said combustion chamber; a supersonic nozzle for extracting products resulting from said combustion fuel-combustion supporter and supplying them into said laser cavity; supply means for supplying singlet oxygen into said laser cavity at the same time as said combustion resulting products; said fuel being in excess with respect to stoichiometric proportions corresponding to said combustion, richness .phi. of said iodine compound fuel with respect to said stoichiometric proportions being 0.5<.phi.<2.5 if the used combustion supporter is F.sub.2 and 0.6<.phi.<2.6 if the used combustion supporter is NF.sub.3 ; the pressure inside said combustion chamber during said combustion being between 50 torrs and 5 bars.
