Contrairement aux lasers CO\u2082 traditionnels, les lasers \u00e0 fibre fonctionnent \u00e0 une longueur d'onde d'environ 1064 nm, ce qui est tr\u00e8s efficace pour le marquage des m\u00e9taux et de certains plastiques.<\/p>\n\n\n\n<p>Le faisceau laser \u00e9tant transmis par des fibres optiques flexibles plut\u00f4t que par des miroirs, le syst\u00e8me est plus stable, plus compact et plus \u00e9conome en \u00e9nergie.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Comment fonctionne un graveur\/marqueur \u00e0 laser \u00e0 fibre ?<\/strong><strong><\/strong><\/h2>\n\n\n\n<p>Le processus de fonctionnement d'une machine de marquage par laser \u00e0 fibre peut \u00eatre divis\u00e9 en plusieurs \u00e9tapes cl\u00e9s :<\/p>\n\n\n\n<p><strong>1. G\u00e9n\u00e9ration de laser<\/strong><strong><\/strong><\/p>\n\n\n\n<p>L'\u00e9nergie \u00e9lectrique excite la fibre optique dop\u00e9e, g\u00e9n\u00e9rant un faisceau laser de haute intensit\u00e9. Ce faisceau pr\u00e9sente une excellente qualit\u00e9 et une densit\u00e9 de puissance \u00e9lev\u00e9e.<\/p>\n\n\n\n<p><strong>2. Transmission par faisceau<\/strong><strong><\/strong><\/p>\n\n\n\n<p>Le faisceau laser est transmis \u00e0 la t\u00eate de marquage par des c\u00e2bles en fibre optique. Cela \u00e9limine l'alignement complexe des miroirs et am\u00e9liore la stabilit\u00e9.<\/p>\n\n\n\n<p><strong>3. Focalisation du faisceau<\/strong><strong><\/strong><\/p>\n\n\n\n<p>Un syst\u00e8me de scanner \u00e0 gal\u00e8ne dirige rapidement le faisceau laser sur la surface de la pi\u00e8ce. Une lentille de champ concentre le faisceau dans un tr\u00e8s petit point, cr\u00e9ant ainsi une concentration d'\u00e9nergie extr\u00eamement \u00e9lev\u00e9e.<\/p>\n\n\n\n<p><strong>4. Interaction des mat\u00e9riaux<\/strong><strong><\/strong><\/p>\n\n\n\n<p>Lorsque le faisceau laser focalis\u00e9 touche la surface du mat\u00e9riau, il provoque un \u00e9chauffement, une fusion, une vaporisation ou une oxydation localis\u00e9s. Cet enl\u00e8vement contr\u00f4l\u00e9 du mat\u00e9riau ou cette modification de la surface cr\u00e9e des marques permanentes et tr\u00e8s contrast\u00e9es telles que :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Num\u00e9ros de s\u00e9rie\uff0cdate<\/li>\n\n\n\n<li>Codes QR et codes-barres<\/li>\n\n\n\n<li>Logos et graphiques<\/li>\n\n\n\n<li>Gravures profondes<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-1024x1024.webp\" alt=\"Graveurs laser \u00e0 fibres\" class=\"wp-image-7557\" srcset=\"https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-1024x1024.webp 1024w, https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-300x300.webp 300w, https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-150x150.webp 150w, https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-768x768.webp 768w, https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers-12x12.webp 12w, https:\/\/www.free-optic.com\/wp-content\/uploads\/2026\/03\/Fiber-Laser-Engravers.webp 1269w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Machine de marquage laser \u00e0 fibre pour la gravure et la d\u00e9coupe de l&#039;aluminium, du cuivre, de l&#039;argent, de l&#039;acier inoxydable et du carbone\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/sV-5uuRUhZU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
