Zusammenfassung:	A clad absorber unit is provided on a passive fiber of a high power fiber laser system and operative to trap and remove high order modes propagating along the clad of the passive fiber. The mode absorber has a composition made from one or more liquid metals and alloys thereof which are placed in the opening formed in the sheath of the passive fiber. The composition is configured to remove from the cladding the MM light having a predetermined light power which heats the composition at a temperature lower than a threshold temperature at which the absorber may be damaged.
