Electro-optical hybrid connection assembly

A laser system comprising:

• a power supply device including a pump light source that outputs a pump laser beam and an electronics unit that outputs one or more electrical signals;
• a connection assembly that receives and transmits the pump laser beam from the pump light source and the one or more electrical signals from the electronics unit, the connection assembly comprising:
• a first connector including a first ferrule that encloses a first optical fiber that receives the pump laser beam output from the pump light source, a centering sleeve surrounding the first ferrule and projecting beyond at least one end of the first ferrule, and at least one electrical plug-in contact connected to a first electrical conductor through which the one or more electrical signals are transmitted, and
• a second connector including a second ferrule that encloses a second optical fiber and at least one electrical plug-in contact connected to a second electrical conductor,
• wherein each of the two optical fibers has a plane fiber end aligned at right angles to an axis of the fibers and when the first and second connectors are connected to each other, the second ferrule is inserted into the centering sleeve such that the second ferrule abuts against the centering sleeve or the first ferrule, the fiber ends of the optical fibers are separated from one another by a gap, and the plug-in contacts are plugged into one another in an electrically conducting manner, and
• a laser head including a laser beam source that receives the pump laser beam that has been transmitted through the second optical fiber and an electrical device that receives the one or more electrical signals that have been transmitted through the second electrical conductor.
