Details Introduction
Based on the unique bismuth element coordinaon atom modulaon technology and valence reducon technology, the silicate based opcal fiber with high gain factor is prepared. The fiber can be used as a gain medium for fiberamplifiers or fiber lasers in O, E,S, L+ and U bands, and is widely used in opcal communicaons, natural environment monitoring and scienfic research.
Features
• High absorpon coefficient
• Highly accurate geometry control
• Low hydroxyl content
• High gain coefficient
ApplicaⅥons
• Opcal communicaons, natural environment monitoring and scienfic research
• Fiber amplifiers and lasers
• Tunable light sources
