1. Spatio-temporally focused femtosecond laser pulses for nonreciprocal writing in optically transparent materials

Author

Vitek, D.N., Block, E., Bellouard, Y.J., Adams, D.E., Backus, S., Kleinfeld, D., Durfee, C.G., Squier, J.A., Vitek, D.N., Block, E., Bellouard, Y.J., Adams, D.E., Backus, S., Kleinfeld, D., Durfee, C.G., and Squier, J.A.

Abstract

Simultaneous spatial and temporal focusing (SSTF)provides precise control of the pulse front tilt (PFT) necessary to achieve nonreciprocal writing in glass wherein the material modification depends on the sample scanning direction with respect to the PFT. The PFT may be adjusted over several orders of magnitude. Using SSTF nonreciprocal writing is observed for a large range of axial focal positions within the sample, and nonreciprocal ablation patterns on the surface of the sample are revealed. Further, the lower numerical aperture (0.03 NA) utilized with SSTF increases the rate of writing.

4. RWTH Aachen University: raising the profile of the University's degree courses on energy and natural resources.

Author

Backus S. and Backus S.

Abstract

Around 900 students have enrolled in courses of the Specialist Group for Raw Materials and Waste Disposal Technology (FRE) at RWTH Aachen University, Germany. The University has a new Bachelor’s Degree course on Sustainable Resources and Energy Supply, which has basic engineering and subject-specific content and options to specialise in sustainable resources from the aspects of mining, recycling, or energy. There are Master’s courses on Sustainable Energy Supply and Raw Materials Engineering and a proposed Master’s Degree course on Sustainable Underground Utilisation. The latter will concentrate on underground space planning and the final disposal of radioactive waste., Around 900 students have enrolled in courses of the Specialist Group for Raw Materials and Waste Disposal Technology (FRE) at RWTH Aachen University, Germany.
