Excimer In laser engraving, an excimer refers to an excited dimer molecule formed by the combination of a noble gas and a reactive gas within an excimer laser cavity. Excimers are short-lived, highly reactive species that rapidly decay to their ground state, releasing photons in the process. The ultraviolet radiation emitted by excimer molecules is utilized for precise material removal and surface modification in laser engraving applications, offering advantages such as minimal thermal damage and high processing speed. |
