Summary
Using fiber optic bundles transmits high-power coherent radiation. Phase correction at fiber ends reestablishes output coherence, enabling efficient power concentration into a focal spot.
Area of Science:
- Optics and Photonics
- Fiber Optics Technology
Background:
- Individual optical fibers have power damage thresholds limiting high-power transmission.
- Transmitting high-power coherent radiation requires specialized fiber optic solutions.
Purpose of the Study:
- To investigate the feasibility of using fiber optic bundles for high-power coherent radiation transmission.
- To determine methods for reestablishing coherence and optimizing power focusing from fiber bundles.
Main Methods:
- Calculated focusing efficiencies for fiber bundles with varying geometric parameters.
- Simulated phase correction techniques for individual fiber ends to restore coherence.
Main Results:
- Fiber bundles can transmit coherent radiation beyond individual fiber damage thresholds.
- Phase correction successfully reestablishes coherence at the bundle output.
- Calculations show realistic power concentration of nearly 40% into the focal spot.
Conclusions:
- Fiber optic bundles offer a viable solution for high-power coherent radiation transmission.
- Effective phase correction is crucial for maintaining and utilizing beam coherence from fiber bundles.
- Optimized fiber bundle geometry and phase control can achieve significant power focusing efficiencies.
