Fiber technology for FCPA
Rod type technology advantages :
- No modal shrinkage due to coiling /
bending
- Ultra-large mode area
- Core / Clad ratio
- Minimized B-integral
- Maximum energy extraction
- Truly single mode
- High optical efficiency
- Proven in the field reliability
Conclusion
Rod type technology remains the key enabler
- 1mJ @ 10 kHz = 10 W
With sufficient stretching today’s industrial high energy FCPA
- Multi-mJ, several tens W, < 300 fs pulse duration
Novel coherent combining approaches
- Spatial CC
- Temporal CC
- Spectral synthesis
Packaging / Beam delivery … To be continued.
