PROBLEM TO BE SOLVED: To provide a femtosecond laser system for the exact machining of material and tissue, in particular a laser apparatus for the precise, micrometer-accurate machining of organic material, preferably an eye.SOLUTION: The system for exact machining of material includes: an apparatus for the exact machining of a material 90, concretely an organic material, comprising a pulsed laser system 10 with a beam source 15 and a cavity-dumped femto second oscillator 11 as beam source; a pulsed laser system with a cavity-dumped femt second oscillator as beam source in which a working beam of the beam source can be applied to the material using a beam apparatus with at least one means for beam deflection; and the pulse emission correlating with the means for beam deflection including means for beam deflection and releasing laser pulses. The purpose can be achieved by the apparatus for exact machining of a material, concretely an organic material.
