Product Description

Durable Nx 1 Pump Coupler for Superior Laser Performance

Product Description

 

An Nx 1 pump combiner is a fiber optic coupler that combines multiple pump lasers into a single output fiber for high-power fiber laser applications. They are also known as pump couplers. 

 

 

Nx 1 pump combiners are essential for building high-power fiber lasers and are used in industrial,medical, and telecommunication markets. They have several features, including: Low insertion loss, High pump power coupling efficiency, and Various input and output fiber options. 

 

 

Nx 1 pump combiners are fabricated using several steps, including fiber preparation, fusion splicing, tapering, and packaging. Fusion splicing is a critical process that creates a joint between the fibers to enable efficient transfer of optical power.

Features
 

• High transmission efficiency
• High stability & reliability
• Custom configuration available

Applications

• High power Optical Fiber Lasers
• Fiber amplifiers
