Product details
Overview
The FT-1400 is a 1000 W fiber-to-free-space optical isolator that protects high-power fiber laser systems from destabilizing back reflections. By converting the fiber output to a free-space beam and passing it through isolating optics, it allows forward light through while blocking light returning into the laser cavity. It is built for high average optical power handling with low insertion loss, and suits fiber laser sources and precision fiber optic instruments.
Key Features
- 1000 W power handling for high-power fiber laser systems
- Fiber-to-free-space isolator design
- High power handling with low insertion loss
- Protects laser sources from back-reflection instability
Applications
- Fiber laser systems and amplifiers
- Fiber optic test and measurement instruments
