Claims16
An airplane or aerospace vehicle system, the system comprising:
- a cockpit section;
- a fuselage section having a first end and a second end, the first end coupled to the cockpit section;
- a tail section coupled to the second end of the fuselage section;
- an optical aperture coupled to the fuselage;
- a high intensity pulse laser generation system configured in the fuselage between the first end and the second end, the system comprising:
- a light source configured to generate a pulse of a laser beam having a pulse energy power of 0.01 Joule to 10 Mega Joule an optical cavity maintained in a vacuum of 300 Torr or less and characterized by a length of free space, the optical cavity being configured to increase an intensity of the pulse from a first energy power intensity to a second higher energy power intensity propagating on a first optical path located within the optical cavity by circulating or reciprocating the pulse along the first optical path;
- an optical path modification device coupled to the optical cavity, the optical path modification device configured to repeatedly change a spatial direction of the pulse propagating on the first optical path at a predetermined timing ranging from 20 milliseconds to 3 seconds, the optical path modification device configured to cause the pulse propagating on the first optical path to change from the first optical path to a second optical path that is outside of the first optical path, wherein the optical path modification device is configured to change a direction of the pulse to the second optical path when the pulse has reached the second higher density thereby generating a high intensity pulse laser beam, and a response time to change to the second optical path is from 0.01 microsecond to 30 microseconds;
- and
- wherein the second optical path traverses through the optical aperture and outside of the airplane or aerospace vehicle.
