Abstract
A system includes a high energy laser (HEL) configured to transmit a HEL beam and a beacon illumination laser (BIL) configured to transmit a BIL beam. The system also includes at least one fast steering mirror (FSM) configured to steer the BIL beam to be offset from the HEL beam. The system further includes at least one Coudé path FSM configured to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.

A system comprising:
- a high energy laser (HEL) configured to transmit a HEL beam;
- a beacon illumination laser (BIL) configured to transmit a BIL beam;
- at least one fast steering mirror (FSM) configured to steer the BIL beam to be offset from the HEL beam;
- and
- at least one Coudé path FSM configured to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.

A jitter correction system comprising:
- at least one fast steering mirror (FSM) configured to receive a beacon illumination laser (BIL) beam and steer the BIL beam to be offset from a high energy laser (HEL) beam;
- and
- at least one Coudé path FSM configured to steer the HEL beam and the BIL beam to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.
A method comprising:
- transmitting a high energy laser (HEL) beam;
- transmitting a beacon illumination laser (BIL) beam;
- steering, by at least one fast steering mirror (FSM), the BIL beam to be offset from the HEL beam;
- and
- steering, by at least one Coudé path FSM, the HEL beam and the BIL beam to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.
