Development and Prospect of High-Power Fiber Laser Chromatic Beam Combining Technology (Invited)
The output power of a single-beam fiber laser has a theoretical limit, and high-power fiber laser beam combining technology is the key to achieving ultra-high power while maintaining high beam quality. This paper analyzes on the limiting factors for power increasing in high-power fiber lasers, and reviews principles, technical characteristics, and current technological statuses of different beam combining schemes. Among these, chromatic beam combining using dichroic mirrors demonstrates significant engineering advantages for power increasing and beam quality preservation in broadband laser systems. The paper reviews the developmental progresses in pulsed and continuous wave fiber laser chromatic beam combining technologies in both domestically and internationally, introduces key technologies and researches in this field. Finally, future prospects for chromatic beam combining technology are discussed.
