The Laser Zentrum Hannover e.V. (LZH) is one of the leading institutions in the field of applied laser research. With approximately 250 employees, basic research, applied research and industrial developments are realised. The Photonic Materials group (PMA) of the Optical Components Department is looking to recruit, at the earliest possible date, a

Research associate (m/f/d) in the field of fundamental investigation of laser-induced destruction processes
Field of specialization: Physics, optical technologies, mechatronics or comparable
(Job-ID: 72207)

The experimental - fundamental investigation of destruction processes of optical functional layers is a current research area of photonics in the BMBF project "Prifusio". The Photonic Materials Group (PMA) conducts research in the field of material development for optical and photonic quantum applications. In order to scale up the power stability, new approaches need to be explored for high-repetition lasers in the petawatt class. The characteristics of the beam sources play a key role in the destruction processes.

You will work as a research associate in collaboration with other researchers in a project both at the LZH and in the overall network on the development of a large laser system for nuclear fusion applications. Their tasks in the project will deal specifically with the measurement of the laser-induced damage threshold (LIDT) of optical components of the target system. The core part will be the setup of the temporally and spatially resolved measurement in order to investigate laser-induced damage to optical components. The measurement procedure must capture both the broadband spectra of the ultrashort pulse laser sources and the statistical character of defect-induced damage. For this purpose, effects over several temporal and spatial orders of magnitude must be taken into account. The experimental results are always compared with the model settings so that direct conclusions can be drawn about the material properties.

The work focuses on:

• Conception, development and setup of experimental procedures for laser-induced destruction of optical components
• Combination of characterization methods for different destruction processes
• Creation and evaluation of scaling models for statistical and deterministic models
• Experimental implementation of the measurement setup, including pump-probe experiments
• Independent organization of their work and communication with project partners

Work environment:

The work in the research group at the LZH offers you an extraordinary environment and the best conditions for a doctorate. We offer:

• A highly motivated, interdisciplinary team in a cooperative working environment
• Independent work in an innovative organization
• Participation in an innovative large-scale research project
• Versatile and exciting tasks
• Insight and integration into current research topics in optical coating
• Close proximity to national and international industry and research partners

Company pension scheme

Requirements:

• A degree (diploma/master's/bachelor's) with above-average grades in information technology, natural sciences, or engineering
• Programming skills (for example, Python, C++, LabVIEW, etc.)
• Optical and mechanical knowledge
• Experience in electronic measurement technology
• Ideally, experience with optical measurement methods, image recognition, and laser technology
• Practical experience with experimental and scientific work
• Interest in independent practical and experimental work
• Good written and spoken English skills
• Sense of responsibility, determination, and reliability

Temporary employment in accordance with the Wissenschaftszeitvertragsgesetz and remuneration is based on the collective agreement for the public service of the federal states depending on qualifications and activities up to TV-L ¾ E13. The possibility of a doctorate is given.

People with severe disabilities are given preference if they are equally qualified.

The LZH emphasizes professional gender equality.
