Summary
We developed a low-loss pigtail reflector for fiber lasers using common parts. This versatile reflector offers adjustable reflection properties, ideal for research and metrology, with minimal signal loss.
Area of Science:
- Optics and Photonics
- Laser Technology
Background:
- Fiber lasers require precise control over reflection properties for various applications.
- Existing methods for adjusting reflection can be complex or introduce significant signal loss.
Purpose of the Study:
- To demonstrate a novel, low-loss pigtail reflector for fiber lasers.
- To provide a versatile and easily adjustable reflection solution for metrological and research applications.
Main Methods:
- The reflector utilizes a dielectric-coated bulk mirror and a Ferrule Connector (FC)-type fiber receptacle.
- Components are secured in a machined holder, allowing controlled pressure for minimal reflection loss.
- The design enables attachment of the fiber's FC connector directly to the mirror surface.
Main Results:
- Achieved a measured reflection loss of only 0.07 dB.
- This loss is significantly lower than typical FC-FC interconnection loss (0.52 dB).
- The achieved loss is comparable to single-mode fiber splice loss (0.05 dB).
Conclusions:
- The proposed pigtail reflector offers a versatile and low-loss solution for fiber laser systems.
- Its design facilitates easy alteration of reflection properties, benefiting research and metrology.
- The method is applicable to a wide range of fiber laser types.
