Beam-Combined Pulsed Fiber Lasers

Charles Yu | 21-ERD-004

Executive Summary

We are developing a beam-combined pulsed fiber laser that will validate a pathway to kilowatt-class average power. This high-average-power device fills a void among high-repetition-rate lasers that is critical for a variety of national security applications such as long-range illumination and isotope separation.
