In one embodiment, a device for capturing radiation includes: a panel defining a plurality of double wedge chambers, wherein each double wedge chamber includes a first wedge-shaped chamber that tapers into an opening for a second wedge-shaped chamber, and wherein a longitudinal axis of the first wedge-shaped chamber is not collinear with a longitudinal axis of the second wedge-shaped chamber.

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.

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.

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.

A laser system (A) is illustrated having a laser cavity () that generates a laser beam (). An outcoupling resonator box () has a reflective mirror () therein. A return resonator box () has a reflective mirror () therein. A first solid window assembly () is disposed between the outcoupling resonator box () and the laser cavity (). A second solid window assembly () is disposed between the return resonator box () and the laser cavity () so that the beam () is directed through the solid window assemblies (), () during operation of the laser system, thereby isolating the usually caustic environment of laser cavity () from that of mirrors (), () that are housed in said resonator boxes (), (), without the use of isolation valves and optical tunnels as in traditional arrangements.

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.
