Onefive GmbH and the
Laser Group of European XFEL, an X-ray free-electron laser in the Hamburg area
that recently started commissioning, have successfully joined their expertise
in the development and commissioning of an all-fiber front-end as part of a
unique laser system for experiments at the new research facility
Onefive brought in its expertise in low-noise ultrafast laser physics, advanced packaging, industrial-grade manufacturing and systematic testing to build an all-fiber laser system. This laser system is seeded with an ultra-low noise femtosecond laser at 1-um with consecutive pulse picking and amplification. It provides dual output ports for multiple beamlines for simultaneously providing the seed and pump line for a noncollinear optical parametrical amplifier. It is bursted with flexible burst time and can provide burst-to-burst variable repetition rate while keeping other parameters constant. It can be completely remote controlled, is integrated in the European XFEL software environment and the laser head is entirely passively air-cooled for low vibration and excellent beam pointing stability.
