US12633719 - Laser beam device with coupling of an illuminating laser beam into an effective laser beam

The patent describes a laser beam device that generates both an effective laser beam and an illuminating laser beam, utilizing a coupling element with distinct sub-regions for each beam. The first sub-region is transparent to the effective laser beam, while the second sub-region reflects the illuminating laser beam, allowing for simultaneous targeting and tracking of an object.

Claim 1

1 . A laser beam device comprising means for generating an effective laser beam originating from the laser beam device, means for generating an illuminating laser beam for illuminating and fine tracking a target, and comprising a coupling element for coupling the illuminating laser beam into a beam path of the effective laser beam to be emitted by the laser beam device, wherein the coupling element has a first sub-region and a second sub-region which is different from the first sub-region, wherein the means for generating the effective laser beam, the means for generating the illuminating laser beam and the coupling element are arranged relative to one another so that the effective laser beam is directed onto the first sub-region and the illuminating laser beam is directed onto the second sub-region, wherein the first sub-region is transparent to the effective laser beam and the second sub-region is designed to reflect the illuminating laser beam in parallel with the effective laser beam in the direction of a target, and wherein the coupling element is designed to transmit illuminating laser radiation reflected from the target.
