Gas dynamic mixing laser

Patent ·
OSTI ID:5709654
A high power gas dynamic mixing laser capable of having an energizing gas formed by an exothermic decomposition process is disclosed. The laser includes a housing having a reaction chamber in which an excitation gas is formed by thermal decomposition of a starting material, a nozzle connected to the housing for expanding the excitation gas to supersonic velocity, means for injecting a lasing gas into the supersonic stream of excitation gas to produce an inversion of populated energy levels of the lasing gas, optical means for extracting a laser beam and exhaust means for passing the gas mixture to the atmosphere. An embodiment of the present invention includes a return duct attached at one end to the exhaust means and at the other end to the housing for circulating the gas through the laser and a lasing gas capable of thermal decomposition downstream the optical means to form the excitation gas.
