Uppsala University Department of Physics and Astronomy


Researcher with Specialization Lasers and Optics

Uppsala University is a comprehensive research-intensive university with a strong international standing. Our ultimate goal is to conduct education and research of the highest quality and relevance to make a long-term difference in society. Our most important assets are all the individuals whose curiosity and dedication make Uppsala University one of Sweden’s most exciting workplaces. Uppsala University has over 45,000 students, more than 7,000 employees and a turnover of around SEK 7 billion.

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over ten divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 125 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.

The Department of Physics and Astronomy invites applications for a researcher position to work with laser and optics for research instrumentation and particle accelerators at the FREIA Laboratory. The Department of Physics and Astronomy is the second largest department at Uppsala University with more than 360 employees and 11 different divisions, situated at the Ångström Laboratory in Uppsala. The department is hosting the FREIA Laboratory that performs research towards future particle accelerators and research instrumentation. The FREIA laboratory operates complex equipment such as cryostats and microwave equipment for testing accelerators and instruments. Current projects focus on the European Spallation Source (ESS), the MAX IV Laboratory, the High Luminosity upgrade of the LHC at CERN, the development of free-electron lasers, and the development of a compact X-ray laser and instrumentation in Uppsala.

The candidate is offered the possibility to work in an exciting modern research area in physics and will have opportunities to interact and collaborate with leading groups in experimental physics and engineering.

Subject Description: The FREIA Laboratory is establishing an experimental area for laser-driven instrumentation for experiments in material science and accelerator applications. The successful candidate will work on three projects during different periods of the employment: (i) the development of a high-harmonic generation (HHG) source, transport and diagnostics of femtosecond XUV pulses; (ii) the development of instrumentation for far-infrared laser spectroscopy; (iii) the development of laser instrumentation for accelerator applications such as a laser undulator.

Work Description: The construction of a photon beamline for femtosecond XUV pulses from an HHG source, the design and implementation of XUV temporal and spectral diagnostics, the development of optical pump – HHG probe capabilities. The construction of an optical transport system for far-infrared laser spectroscopy, the development of detectors for spectroscopy. The development of laser transport, focusing and synchronization for accelerator applications. Support for user experiments. Regular presentations of the results in the presence of specialists on different topics, in Uppsala or at other laboratories. Assist in the overall development and evaluation of instrumentation and experiments at the FREIA Laboratory. Actively contribute to outlook activities and education and supervision of students. Regular travel is required for national and international projects.

Prerequisites: The applicant must have a doctoral degree, at the start of employment, in physics or a related area. You shall demonstrate a drive and determination to achieve results, be open minded and flexible in relation to the type of work assigned. You shall take responsibility, shall organize multiple tasks simultaneously, and have a genuine interest in research and technology.

The following knowledge, experience and competencies are required:

  • Solid knowledge of modern laser technologies.
  • Solid experience of operation of lasers and laser diagnostics.
  • Solid experience of designing and building optical transport systems in different photon energy ranges.
  • Solid experience of optical measurements and ability to perform a solid error analysis.
  • Willing to work as part of a multi-disciplinary team.
  • Effective ability to lead work.
  • Very motivated, innovative and curious.
  • Strong ability to think creatively and combine ideas and topics from different areas.
  • Ability to read and understand technical information.
  • Ability to communicate well both technically and at a general scientific level.
  • Ability to produce good written work and reports.
