OPTICAL ROTATING DEVICE FOR INJECTING A LASER BEAM AND METHOD FOR POSITIONING A LASER BEAM

摘要

An optical rotating device for injecting a laser beam may include deflection devices between which the injected laser beam may rotate in the optical rotating device, and an extraction device that may extract the laser beam after carrying out a predetermined number of rotations in the rotating device. The deflection devices may be arranged such that the position of the laser beam during extraction is dependent on the number of rotations carried out in the optical rotating device.

1. An optical circulation device for coupling in a laser beam, comprising:
deflection devices, between which the coupled-in laser beam carries out circulations in the optical circulation device, and an out-coupling device configured for coupling out the laser beam after the laser beam has carried out a predetermined number of circulations in the circulation device, wherein the deflection devices are designed and arranged in such a way that the position of the laser beam when coupling out depends on the number of circulations carried out in the optical circulation device.
