Abstract
A self-powered laser system for discharging high energy light beams is disclosed. The laser system includes a laser unit, a power unit, and an exhaust system. The laser unit is capable of discharging beams in multiple directions. The exhaust system directs exhaust gasses discharged from the power unit.
Claims20
A laser system comprising
- a laser unit configured to discharge high energy beams in multiple directions,
- a power unit coupled to the laser unit and configured to provide pulses of electrical power to the laser unit, the power unit including a gas turbine engine and an exhaust conduit configured to conduct exhaust gasses produced during operation of the gas turbine engine, and
- an exhaust system configured to direct the discharge of exhaust from the exhaust conduit, the exhaust system including an exhaust director and a controller, the exhaust director being reconfigurable from a first configuration in which the exhaust director causes exhaust gas to move in a first direction as it exits the exhaust conduit to a second configuration in which the exhaust director causes exhaust gas to move in second direction as it exits the exhaust conduit, and the controller being coupled to the exhaust director to reconfigure the exhaust director from the first configuration to the second configuration in response to receipt of information associated with high energy light beam guidance so that exhaust gas interference with the high energy light beams from the laser unit is managed.
A generator system adapted for use with a laser unit adapted to produce high energy light beams, the generator system comprising
- a power unit power unit including a gas turbine engine and an exhaust conduit configured to conduct exhaust gasses produced during operation of the gas turbine engine, and
- an exhaust system configured to direct the discharge of exhaust from the exhaust conduit, the exhaust system including an exhaust director that directs exhaust gas as it exits the exhaust conduit and a controller coupled to the exhaust director,
- wherein the controller is configured to reconfigure the exhaust director to change direction of exhaust gas as it exits the exhaust conduit in response to receipt of information associated with high energy light beam guidance so that exhaust gas interference with the high energy light beams from an associated laser unit is managed.
A laser system comprising
- a laser unit movable to discharge high energy light beams in multiple directions,
- a power unit coupled to the laser unit and configured to provide pulses of electrical power to the laser unit, the power unit including a gas turbine engine and an exhaust conduit coupled to the gas turbine engine to conduct exhaust gasses produced during operation of the gas turbine engine, and
- an exhaust system configured to direct the discharge of exhaust from the exhaust conduit, the exhaust system including an exhaust director that directs exhaust gas as it exits the exhaust conduit and a mechanical linkage that extends from the laser unit to the exhaust director,
- wherein the mechanical linkage couples the exhaust director to the laser unit such that the exhaust director is moved to change direction of exhaust gas as it exits the exhaust conduit in response to movement of the laser unit so that exhaust gas interference with the high energy light beams from the laser unit is managed.
