Flexible laser fine processing of technical thin glass

Innovations & Projects
Funding project: Flexible laser fine processing of technical thin glass / to be seen: two hands with two puzzles, the logo of the EU and the logo of the Free State of Thuringia

Development of industrial processes for flexible processing of technical thin glass with the highest precision requirements.

Project duration: 03/2024 to 02/2026

LCP has many years of experience in processing hard-brittle materials, in particular technical ceramics. However, the existing innovative system technology, laser sources and processes cannot be adapted 1:1 to hard-brittle materials that are transparent in the visible spectral range, such as technical glasses or transparent ceramics. 

The aim of the project is to develop industrially suitable processes for the flexible processing of technical thin glass from 0.2 mm to approx. 2 mm material thickness. This is to take place within the framework of a pure two-year R&D activity at LCP. Various laser processes for processing transparent materials are to be newly introduced and further developed for industrial use. These include filamentation using Bessel beam optics and possibly additional thermal shock processing. The possibilities of backside processing and high-power ultrashort pulse (ultrashort pulse) laser processing for various types of glass are also to be developed with process reliability. In particular, various beam shaping and beam guidance components must be evaluated for this purpose.

 

In accordance with the guidelines of the Free State of Thuringia, the company receives funding to secure and recruit highly qualified personnel for research and development and innovation (FTI-Thuringia PERSONNEL guidelines). Funding is provided from the European Social Fund Plus (ESF+) and from state funds of the Free State of Thuringia.
