Influence of temporal parameters of laser irradiation on emission spectra of the evaporated material

The invention relates to a cutterhead for vegetation cutter apparatus and has as its object to configure the cutterhead so that the cutterhead as a unit can be built so as to be overall constructively small and reduce wear. The cutterhead controls the spool having the filament with the aid of a latching lever. To achieve an overall construction which is small and subjected to less wear, the invention provides at least one pivot lug fixedly mounted on the housing having its latching lever arranged in an annular space lying concentric to the rotational axis between the hub of the cutterhead and the switching cams corresponding to the filament spool. These switching cams lie in the outer radial region of the spool.
