摘要

The method involves irradiating an upper surface of an object with one or multiple laser pulses, in order to remove an upper surface section. The material is irradiated with one or multiple other laser pulses, where the material is laid on under the upper surface section. Both laser pulses are generated with an individual pulsed laser by repeated quality switch during a pump cycle of the pulsed laser. The former laser pulses are adjusted with long laser pulse duration than the latter laser pulses. An independent claim is included for a device for preparing laser material removal, particularly for executing a laser-emission spectrometry.
