Nonlinear High-Energy Pulse Propagation in Graded-Index Multimode Optical Fibers for Mode-Locked Fiber Lasers.

摘要

The main objective of the proposed research has been to investigate the proper integration of large-core graded-index multimode fibers (GIMFs) in ultrafast mode-locked fiber lasers to dramatically increase the pulse energy. Detailed theoretical investigations are aimed equally at developing a fundamental understanding of pulse propagation in GIMFs, as well as providing key opportunities to enhance the performance of ultrafast mode-locked fiber lasers.
