Advanced Splicing and High-Resolution Imaging Facility for High Power PCF Laser Fabrication.

摘要

Monolithic fiber lasers systems are highly desirable for defense and industrial applications due to their excellent beam quality, high efficiency, ruggedness, and compactness. Photonic crystal fibers (PCF) with large mode field diameters are a promising technology for further power scaling of current high power fiber lasers and amplifiers. However, the integration of PCFs into efficient and reliable all-fiber laser systems is a significant challenge. Firstly, high-performance PCF required for high power operation are difficult to manufacture. Secondly, PCF splicing and fused components processing (pump combiners, mode adaptors, output couplers, and end caps) require nonconventional splicing technologies. High power fiber laser development for the nation's high energy laser program, is a core component of the Townes Laser Institute (TLI).
