Abstract: The invention relates to a device for inscribing identification plates (16) with a laser inscribing device, a support plane (14) for the identification plates (16), a writing head (20) for applying the inscription to the identification plates (16) and a displacement unit (18) for displacing the writing head (20) over the support plane (14). According to the invention, the laser inscribing device comprises a resonator (26) and a fixed pumped light source, physically separate from the resonator (26), connected to the resonator (26) by means of a waveguide (28) and the resonator (26) forms part of the writing head (20), or the laser inscribing device comprises a fibre laser (40) and an optic fibre (42), wherein the optic fibre (42) is connected at the first end thereof to the resonator of the fibre laser (40) for injecting the light emitted thereby and connected at the second end (44) thereof to the writing head (20).
