Target marker having quantum cascade laser for thermally marking a target

摘要

A portable target marker includes a quantum cascade laser configured to generate a thermal infrared beam. The target marker also includes a driver operably connected to the quantum cascade laser and configured to pulse the beam at a desired repetition rate. The pulsed beam intersects a target. The target marker further includes a thermal imager configured to form a visible image of the pulsed beam intersecting the target.
