Nonminimum Phase Behavior of Laser Material Processing
Optical sensors are increasingly applied in laser material processing to monitor and control the lasermaterial interaction zone. Dynamic models, relating the sensor signals (e.g. as temperature or molten area) to the process inputs (e.g. laser power or beam velocity), provide the basis for the design and tuning of a feedback controller. These models can show nonminimum phase (NMP) behavior. Thi...
متن کاملAdaptive Optics Control for Laser Material Processing
An adaptive optics system is used for correcting tip-tilt disturbances in an experimental laser material processing setup. The proposed tip-tilt controller is based on PI-controllers that are fed with disturbance estimates from a Kalmanfilter. In addition, delays due to wavefront computation in the wavefront sensor and from data transmission are taken into account in the loop-shaping design. La...
متن کاملTubular filamentation for laser material processing
An open challenge in the important field of femtosecond laser material processing is the controlled internal structuring of dielectric materials. Although the availability of high energy high repetition rate femtosecond lasers has led to many advances in this field, writing structures within transparent dielectrics at intensities exceeding 10(13) W/cm(2) has remained difficult as it is associat...
متن کاملImage Processing Based Calibration of High Precision Laser Projection Systems
Large-scale laser projection systems used in industrial environment, e.g. for the projection of CAD drawings onto large work pieces, require external calibration to ensure constant precision and hence quality. Basically, each different projected pattern has to be calibrated at least once, to account for temperature-induced variations in the laser scanning systems, relative displacements due to ...
متن کاملUltrafast laser material processing using dynamic temporal pulse shaping
Phase manipulated ultrafast laser pulses and temporally tailored pulse trains with THz repetition rates are promising new tools for quality micromachining of brittle dielectric materials, allowing to adapt the energy delivery rate to the material properties for optimal processing quality. The sequential energy delivery with judiciously chosen pulse trains may induce softening of the material du...
