High power line generating diode lasers

摘要

Large area laser assisted surface treatment greatly increases process velocity and productivity by optimizing or finishing function layers, e.g. for window glass or in the flat panel display industry. Uniform and consistent processing as a result of homogeneous intensity distribution of the beam profile is a general demand for long laser beam lines. However, for each specific application the individual needs are different with respect to optical power, beam line length or wavelength. The three key parameters are: High power density per line length, small line width and long line lengths. The challenge in the design process is to generate basic building blocks, which allow scalability in both, optical power and line length. We give an exemplary overview about scalability concepts of line generating laser modules.
