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

Page 17: Ultrafast lasers for scientific, industrial and medical ...

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.
