演讲摘要：

Laser processing with ps-lasers is generally known for very low thermal influence, precise energy processing and the possibility to ablate every type of material independent on hardness and vaporisation temperature. The use of ultra-short pulse lasers offers new possibilities in the manufacturing of high-end products with extra high processing qualities. By a variety of materials, the processing results, especially the quality and processing efficiency can further be improved by using lasers with pulse length in fs region. So far, we have accomplished the micromachining of small parts like components in display, printing, electronics and semiconductor. There is huge potential to scale the precision processing to macro parts. There is huge potential to scale the precision processing to macro parts. One major key for success is the investigation and understanding of interaction between material and ultra-short laser pulses. This is the basis for finding processing strategy. It is obligatory to monitor and control the process. Other major challenges are: scaling the power of ultra-short pulse, beam engineering; improving performances of optical components under high power/energy load; developing technology for delivering and handling of high power/energy beams. For transferring micro precision to macro parts there is no generally applicable solution. Instead, solutions will be tailored and application specific. In this talk we will present and discuss - Basic understanding of interaction between material and ultra-short pulses - Specific aspects of ultra-short pulse lasers - Examples of applications and system solutions
