Paper Abstract

During the first 20 years of TRUMPF’s existence as a laser company, it developed a reputation for standard products for applications, now referred to as the traditional industrial applications: laser cutting and welding of steel and aluminum. During the same time, TRUMPF acquired five basic technology platforms – fast-flow and diffusion-cooled CO2 lasers, thin disk, diode and fiber lasers. The standard products cover only a small section of the multi-dimensional parameter space that can be covered with these five basic technologies. These platforms, however, provide enormous flexibility and highly reliable building blocks that are now used to fill white areas in the parameter space, enabling novel applications unrelated to the original applications for these technologies. Presented are some examples of how the scaling of these technologies has led to unique and novel laser devices and applications. They include the generation of EUV with CO2 lasers, short-pulse applications with diffusion-cooled and fast-flow CO2 lasers for processing of composite materials and plastics. Laser output power, the traditional main characteristic for CO2 lasers, made way for pulse energies, pulse lengths and wavelength. The traditional cw thin disk laser platform was transformed into short and ultra-short pulse lasers with wavelengths down to 343 nm. Diode lasers evolved from low brightness pump sources for thin disk lasers to diode direct lasers. This flexibility will ensure that remaining white spaces in the parameter space can be filled in the future as required.
