Abstract
We report on applications of Yb3+-doped fiber-laser systems in the micro-processing and the markign of different materials. We have demonstrated the drilling of small holes in glass slides with a thickness of 1 mm using a fiber-laser system wtih an otuput-power of about 35 watts. Furthermore, we have used a narrowband fiber-laser system with an output-power of a few watts for the marking of thin plastic films and samples of anodized aluminum. These applications are based on the experience of more than 10 years in the design, development and preparation of rare-earth doped double-clad silica fibers at the IPHT e.V. Jena. We systematically have optimized the composition and the geometry of these specialty fibers. So we could manufacture very efficient samples which were tested in several fiber-laser setups with output-powers of up to almost 200 watts. Especialy, in the high-power region we could solve some thermal problems using new concepts for the double-clad fiber cross section. We successfully designed, prepared and tested so-called Large-Mode-Area fibers as well as fibers with two or mroe refractive indices in the pump-core. Additionally, we increased the available pump-power of the one-end-pumped fiber-laser systems using a wavelength-multiplexed diode-laser fiber-coupled system.
