Abstract: A device for reshaping a laser beam may include a first optical element to receive the laser beam. The device may also include a second optical element to invert and reshape the laser beam to substantially correspond to a aperture of a beam director.

Abstract: A system and method for errant laser beam detection are provided for effectively detecting small coating failures in a cost effective and robust manner. In one embodiment, a detection system includes a continuity circuit on a printed circuit board (PCB) having metal (e.g., copper) traces which are designed to burn through if an errant beam strikes them. The traces are sized and patterned appropriately to sense a minimum subaperture size.

Abstract: An exemplary calorimeter includes a body configured to capture radiation generated by a source of the radiation, such as without limitation a laser, and absorb energy from the captured radiation. The calorimeter is simple to manufacture, operate, and maintain and is compact, highly accurate, able to withstand high power beams, and self-calibrating. NIST traceable electrical wires are used for the measurement. No fluids are used during measurements of the input radiation. A simple built in fluid or gaseous cooling system may be used post-measurement to reset the calorimeter temperature back to ambient for repeated measurement capability.

Abstract: A device for capturing radiation includes multi-axis, multiple chambers with two dimensional geometry. A first chamber has a first axis and is configured to receive a beam of radiation and absorb a portion of the beam of radiation. A second chamber has a second axis that is not collinear with the first axis. The second chamber is configured to receive at least a portion of the beam of radiation and absorb at least a portion of the beam of radiation. In one preferred embodiment, the second chamber terminates at a vertex. Additional chambers may be provided, as desired, with axes not collinear with either the first chamber, the second chamber, or any other chamber such that the plurality of chambers absorb substantially all of the radiation.

Abstract: An apparatus 10 for positioning a laser mirror 16 secured within mirror mount 14. A centrally disposed linear actuator 20 is positioned to impart a force to the mirror mount 14 which is in line with the net center of percussion of the laser mirror 16 and mirror mount 14, thus providing tip/tilt free single point piston actuation. Three tip/tilt actuator assemblies 18,76 equidistantly disposed about the linear actuator 20 provide coarse adjustments and fine tip/tilt actuation. The mirror mount 14 is resiliently connected to the base 12 by support means 24,54.
