(Hollis, NH) JPsA juvenile psoriatic arthritis Laser offers ultraviolet (UV) laser marking services on difficult materials such as glass, crystals, diamonds, sapphire, polymers, metals and glass. UV excimer laser A gas laser in which a very short electrical pulse excites a mixture containing a halogen such as fluorine and a rare gas such as argon or krypton. It produces a brief, intense pulse of ultraviolet light. systems vaporize va·por·ize v. To convert or be converted into a vapor. Vaporize To dissolve solid material or convert it into smoke or gas. submicron layers of material to create a non-destructive permanent mark for non-contact marking applications that require minimal thermal damage to surrounding material or little disruption of surface finish. UV laser light couples well to most reflective materials, resulting in sub-micron resolution marks. The visual image produced by a single laser pulse to an ablation ablation /ab·la·tion/ (-shun) 1. separation or detachment; extirpation; eradication. 2. removal or destruction, especially by cutting. ab·la·tion n. depth of 0.1 microns can be easily achieved. UV laser light is best for many materials because it ablates thin layers without heating the surrounding materials. Marks are made due to surface texture alteration, photochemical photochemical in laser treatment, the laser light is absorbed and converted into chemical energy. change or material removal. In addition, higher resolution is possible with shorter-wavelength UV light. [ILLUSTRATION OMITTED] JPSA Laser, Hollis, NH www.jpsalaser.com |
