Abstract
A beam terminator for a high-power laser beam comprises a thermally conductive body including a beam-trapping chamber. A tapered spiral channel extends into the conductive body for guiding the beam. The beam is partially absorbed while propagating along the channel to the trapping chamber. What remains of the beam is absorbed in the trapping chamber.
