Abstract
Ultrafast beam delivery based on micro structured hollow-core fibers is now regularly used in industrial applications. It enables stable multi-axis applications with ultrashort pulses for highest precision and demanding materials. With the increase in readily available laser sources incorporating a second harmonic module and more material processes being investigated which benefit from shorter wavelength, the beam delivery has to be adapted to these new laser sources. Transmission in the green spectral range can now be transmitted with a flexible hollow-core fiber. Recent results transmitting high energy pulses from an SHG source will be shown. Additionally, as laser sources increase in available power, transmission and handling of ever increasing light pulses is of interest as well as polarization maintaining transmission of ultrashort pulses. We show recent results which include solutions for highest power delivery and operation with stable polarization at the output.
