Método para el proceso de microperforación de pulso único con un cabezal láser, cabezal láser y máquina de microperforación

A method for the single-pulse micro-perforation process with a laser head, a micro-perforation machine with a laser head, and a laser head, comprising a nozzle and a Foucault current sensor disposed in the nozzle and concentric therewith, level with a first end of the nozzle; the Foucault current sensor comprising: an electrically conductive coil at a distance from an opening in the nozzle greater than or equal to 4.0 mm; a separator member disposed such that a first side of same is facing the electrically conductive coil and a second side thereof is facing a work piece the distance whereof with regard to the Foucault current sensor it is desired to measure; and a diameter Φ of a cable that forms the electrically conductive coil is: 0.30 mm ≤ Φ ≤ 0.45 mm.
