Abstract
An optical architecture for a high-energy laser that directs a collimated laser beam through an aperture stop at a desired angle. In one embodiment, the optical architecture includes a single tilt mirror and three stationary mirrors that direct the laser beam in one dimension. The laser beam is reflected off of the mirrors in the same plane and is reflected off of the tilt mirror three times. The first two reflections off of the tilt mirror translate the beam and the third reflection causes the beam to be directed at the desired angle. In another embodiment, the optical architecture includes a single tip-tilt mirror and eight stationary mirrors that direct the beam in two dimensions. The laser beam is reflected off of the mirrors in two planes and is reflected off of the tip-tilt mirror three times. The first two reflections off of the tip-tilt mirror translate the beam and the third reflection causes the beam to be directed at the desired angle.
