Abstract: In order to improve a laser amplifying system comprising a solid-state member having a laser-active medium, a radiation field system determined by an optical guide means for the radiation field and an actively switchable, optical switching element arranged in the radiation field system for influencing the losses in the radiation field system in such a manner that this is suitable for low-amplification laser-active media, it is suggested that the solid-state member be designed like a thin plate, the radiation field system comprise an incoming branch and an outgoing branch which are coupled to one another, on the one hand, and between which, on the other hand, an amplifying radiation field is provided which is formed from a plurality of intermediate branches which extend between two optical beam reversing elements and, for their part, all penetrate the solid-state member in a direction transverse to its flat sides and within an active volume area, and that the active volume area have in directions transverse to

Abstract: The invention provides a network system for laser processing, comprising at least two laser devices and a workstation with a laser processing head which can be operated safely. A first light guide leads from the first laser device to a first connection element, associated with which is a first communication connection element connected to the laser controller of the first laser device. A second light guide leads from the second laser device to a second connection element, associated with which is a second communication connection element connected to the laser controller of the second laser device. The laser processing head can be connected to one of the connection elements by a mating connection part. A safety circuit of the workstation ensures that each laser controller releases the shutter switch only if the safety circuit is connected to the communication connection element connected to the respective laser controller.
