ーザ光伝送装置。In a laser beam transmission device comprising a condensing lens that condenses a laser beam output from a laser oscillator using an optical system and enters an optical fiber, and condenses the laser beam emitted from the optical fiber onto a workpiece, the optical The system consists of a plurality of condensing lenses with different focal points. Among these condensing lenses, the short focus lens is located in the area where the average output of the laser beam is high, and the long focal length lens is positioned in the area where the average output is low. A laser beam transmission device characterized in that it is installed so that it can be inserted and removed freely.
