At Helmut Schmidt University / University of the Federal Armed Forces Hamburg (HSU/UniBw H), Faculty of Electrical Engineering, Professorship for Laser Technology (Univ.-Prof. Dr. Pronin), a position is available from the next possible date for a
Research Assistant (m/f/d)
(salary group 13 TVöD [Collective agreement for the public service]; 39 hours per week)
for a limited period of 2 years.
The research activities of the professorship are focussed on basic civil laser research with a particular focus on applications in spectroscopy. Our topics range from the development of powerful disc laser oscillators and XUV frequency combs to the investigation of non-linear effects in multipass cells and laser-matter interaction at pulse durations below 50 fs (1 fs = 10-15 s). The newly developed laser systems and spectroscopy methods offer a broad application potential in precise XUV spectroscopy, spectroscopy with ultrashort la-ser pulses and ultra-precise next-generation material processing.
The position offered focuses on next-generation ultra-precise material processing with pulses of less than 50 fs at a wavelength of 1030 nm and its harmonics (515 nm, 343 nm). We plan to investigate various transparent materials such as glasses, polymers and ceramics and explore ablation, cutting and non-linear refractive index changes. Selective etching will be used to clean the surface and create holes and channels in the glass materials for future chip packag-ing applications. Ablation and cutting are performed using galvo scanner systems and specialised XY translation stages with nanopositioning accuracy.

QUALIFICATION REQUIREMENTS

• A completed university degree (Diplom [univ.] or Master) in the field of physics or engineering
• Experience with nonlinear optics, namely, second and third harmonic generation with femtosecond pulses
• Experience with ultrashort pulse characterization techniques such as autocorrelator or FROG
• Experience with electronics and programming of microcontrollers

• Research into various non-linear conversion processes for 1030 nm fundamental wavelength with the goal to generate highest efficiency second and third hamornics at <50 fs pulse duration
• Study interactions of <50 fs pulses at 1030 nm, 515 nm and 343 nm with different materials. Systematically analyze the results with laser scanning microscope, electron microscope and make the data evaluation
• Systematic analysis of the results using a laser scanning microscope and an electron microscope and evaluation of the data
• Application of the developed technologies in drilling, cutting and other processes with industrial relevance • Assistance in teaching to the extent of basically 3,0 trimester hours per week • Possibility of further academic qualification (e.g. doctorate or habilitation)
• Carrying out general administrative work as well as academic activities in academic self-administration
