Abstract: A system for producing singlet delta oxygen has a source of liquid oxygen. A reactor has an input connected to the source of liquid oxygen. An optical pump is connected to an optical input of the reactor. The system can be by used as a laser by placing an optical resonator and a source of molecular iodine near the output of the reactor.

Abstract: A tunable solid state laser has an optical quality solid material impregnated with a halogen dopant. An optical cavity resonator contains the solid material. An optical excitation source is coupled to the solid material. The doped material has additional applications as a coating to produce white light from blue light emitting diodes.

Abstract: A generator produces a flow of gaseous molecular oxygen in the singlet sigma and/or singlet delta excited electronic states. The generator is comprised of an optical source; coupling optics to transport and concentrate optical source light; a vacuum chamber, reflective optics; a wall cooling system; an inlet system for injecting oxygen; an inlet system for injecting other gases which deactivate singlet sigma oxygen to singlet delta oxygen; and a means for interfacing this device to a lasing device and for directly flowing the singlet sigma or singlet delta oxygen into a laser cavity.

Abstract: An oxygen-iodine laser system that includes a source of gaseous singlet delta oxygen O.sub.2 ('.DELTA.) and a source of gaseous iodine monochloride, ICl, that directs their respective gases to manifolds and then to a mixing reacting nozzle. The nozzle discharges the mixed gases into a lasing cavity. When mixed the ICl dissociates into atomic iodine, I, and atomic chlorine, Cl, in the presence of the excited oxygen. The atomic iodine is subsequently excited to I(.sup.2 p1/2) lasing state by the excited oxygen. The lasing cavity, which includes optical means for extracting radiation, includes exhaust ports connected to an exhaust system. The advantage of using ICl in the laser rather than conventional source of atomic iodine is that for a given temperature the operating pressure of the laser can be higher without encountering efficiency reducing condensation of the iodine.

Abstract: A scanning system for mapping the degree of uniformity of gas flow in the cavity of a laser includes a carriage mounted for movement along a set of parallel tracks disposed along a side of the laser cavity. The carriage mounts an infrared detector in radiation receiving relationship with the laser cavity. A screw drive mechanism is drivingly coupled to the carriage for moving it in opposite directions on the tracks. Spaced windows along the side of the laser cavity allows passage of radiation from the laser cavity to the detector. Because of the alternating relationship between transmissive windows and non-transmissive plates which defined the windows, successive portions of a voltage signal generated by the detector representing separate measurements can be easily identified with successive positions of the carriage along the laser cavity, and thus with particular successive portions of the laser cavity where each measurement was taken.
