Abstract:
A Chemical Oxygen-Iodine Laser (COIL)/cryosorption vacuum pump system comprising:(a) a COIL including a laser cavity; and,(b) a cryosorption vacuum pump system for removing exhaust gases from said laser cavity at a rate and sufficiently low pressure to sustain lasing action, said cryosorption vacuum pump system, comprising:(i) a gas chiller assembly for chilling a flow of laser gases received from said laser cavity, said gas chiller removing condensable vapors therefrom, said condensable vapors including water and iodine, said gas chiller providing cold dry laser gases;(ii) a cryosorption assembly including a bed of cryosorption material for receiving and absorbing said cold dry laser gases from said gas chiller;(iii) means associated with said gas chiller assembly for refrigerating said gas chiller assembly;(iv) means associated with said cryosorption assembly for refrigerating said bed of cryosorption material; and(v) means for regenerating said gas chiller assembly and said cryosorption assembly by removing the condensable vapors and laser gases therefrom.
