Zusammenfassung:A device for transporting pulsed laser radiation includes a pulse duration setting device configured for setting a transport pulse duration of the pulsed laser radiation. the device further includes a hollow core optical fiber having a hollow core surrounded by a material. The hollow core optical fiber is configured to be operated with beam path parameter values that are present at the first fiber end and lie in a target tolerance range. The device further includes a fiber input coupling device configured to couple the pulsed laser radiation into the hollow core optical fiber with the beam path parameter values that lie in the target tolerance range. the transport pulse duration is set so that input coupling of the pulsed laser radiation into the hollow core is provided for all of the beam path parameter values in the target tolerance range.
