Transfer device for coupling laser radiation between optical fibers, has lens system with at least 3 optical elements that transfer high power laser light under-focused or with exact imaging

摘要

The device has a lens system (10) consisting of optical components arranged between the end surface of the first optical fiber (11) and the end surface of the second optical fiber (12). At least one lens system consisting of at least three optical elements transfers high power laser light from one fiber end surface to the other under-focused or with exact imaging.
