Review of self-focusing of high power lasers in large-mode-area optical fibers

Abstract

The main progress about the self-focusing of high power lasers in large-mode-area optical fiber has been reviewed. The theoretical models including the self-focusing effects have been discussed. Some different views on the whole beam self focusing and small scale self-focusing effects in optical fiber have been introduced. Moreover, the possible methods exceeding the bulk-media self-focusing threshold have been discussed and explored.
