We report on the recent design and fabrication of kagome-type hollow-core photonic crystal
fibers for the purpose of high-power ultrashort pulse transportation. The fabricated seven-cell …

Ultrafast lasers based on fiber optic architecture and integrated software controls will play a
dominant role in the spread of these lasers into commercial and industrial applications. The …

… When Michael Mielke invited me to write this preface, I accepted without reservation. … I
want to commend Michael Mielke and Marcus Gebauer for outstanding contributions to the …

A monolithic fiber chirped pulse amplification system that generates sub-500 fs pulses with
913 µJ pulse energy and 4.4 W average power at 1.55 µm wavelength has recently been …

We demonstrate high average power, high energy 1.55 μm ultra-short pulse (<1 ps) laser
delivery using helium-filled and argon-filled large mode area hollow core photonic band-gap …

This paper shows how we developed a 7-Steps-Method to determine, measure and improve
DQ in our team. Based on an actual business process description, we worked out the …

Energy scaling of femtosecond fiber lasers has been constrained by nonlinear impairments
and optical fiber damage. Reducing the optical irradiance inside the fiber by increasing …

In the evaluation a fused biconical taper 1480/1580 nm WDM’s ability to handle high power
cascaded Raman laser throughput (>100 W) a significant degradation in performance was …

A novel monolithic fiber-optic chirped pulse amplification (CPA) system for high energy,
femtosecond pulse generation is proposed and experimentally demonstrated. By employing a …
