Details Introduction
Product DescripⅥon
Double cladding Tm-doped fiber is composed of opmized fiber preparaon process and high- performance glass. The fiber is an acve fiber used in 2μm band fiber lasers and fiber amplifiers, and has the characteriscs of high absorpon coefficient and high light conversion efficiency of 793 nm pump. It can be widely used in plascs processing, medicine and scienfic research.
Features
• High precision geometry control
• High 793 nm pump laser slope efficiency
• Reliable stability in high temperature and high humidity environments
ApplicaⅥons
• Plascs processing, medicine and scienfic research
• Connuous/pulsed fiber lasers and amplifiers
