PCT No. PCT/EP96/04187 Sec. 371 Date May 16, 1997 Sec. 102(e) Date May 16, 1997 PCT Filed Sep. 25, 1996 PCT Pub. No. WO97/12429 PCT Pub. Date Apr. 3, 1997A double-core light-conducting fiber comprise a pump core, a laser core which is arranged centrically in the pump core, and a cladding surrounding the pump core. The pump core which is constructed with a substantially circular cross section has at least one ground portion on the outside which extends in the light direction of the double-core light-conducting fiber and amounts to 1% to 49% of the diameter of the pump core. A process for the production of the double-core light-conducting fiber and to a double-core fiber laser and to a double-core fiber amplifier are also disclosed which use the double-core light-conducting fiber according to the invention. The substantially round pump core with its centrically arranged laser core enables a simple connection with other fiber-optic components and a simple coupling in of the pumping light.
