Zusammenfassung:	The present disclosure relates to a device (500) for distance measurement for a laser processing system (100). The device (500) comprises a light source (510), which is designed to produce a primary beam for directing at a workpiece (1), at least one detection device (520), which is designed to detect a secondary beam reflected by the workpiece (1), at least one optical amplifier (530), which is designed to amplify the primary beam and/or the secondary beam, and an evaluation unit, which is designed to evaluate interference of spectral components in the frequency range. La présente invention concerne un dispositif (500) de mesure de distance pour un système de traitement au laser (100). Ledit dispositif (500) comprend une source lumineuse (510) qui est conçue pour générer un faisceau primaire destiné à être dirigé vers une pièce à usiner (1), au moins un dispositif de détection (520) qui est conçu pour détecter un faisceau secondaire réfléchi par la pièce (1), au moins un amplificateur optique (530) qui est conçu pour amplifier le faisceau primaire et/ou le faisceau secondaire, et une unité d'évaluation qui est conçue pour évaluer une interférence entre des composantes spectrales dans la plage de fréquences.
