Abstract
Provided is a high-power laser beam transmitter including a depolarizer. The present invention includes a high-power laser generator that generates a high-power laser beam, a beam transmitter that delivers, to an optical fiber, the laser beam emitted from the high-power laser generator, and the optical fiber disposed at the output end of the beam transmitter to receive the laser beam, wherein the beam transmitter includes a plurality of lenses and a depolarizer including a plurality of depolarizers respectively disposed between the plurality of lenses. By disposing the depolarizer and thus reducing the constructive interference occurring when the high-power laser beam is incident on the optical fiber, damage to the optical fiber due to high instantaneous output may be attenuated.
Claims4
