Photonic Tools has developed a robust, fiber-bonded laser guidance system for ultrafast lasers, which guarantees the highest possible transmission while preserving the laser beam parameters. The trick: The laser beam is directed through "nothing". For this we use the latest generation of micro-structured hollow-core fibers.
