• Oliver HECKL - Optical Metrology: Mid-IR fiber lasers and frequency combs

  This fully funded PhD position involves delving into the research and development of ultrafast mid-IR frequency combs, with a specific focus on the 4I_11/2à4I_13/2 Er³⁺ transition. The successful candidate will be responsible for developing a laser that operates at a wavelength of 2.8 µm, with the stability required for open-air spectroscopy, making this laser a tool in the study and mitigation of climate change. 

  Throughout the course of your PhD, you will gain valuable experience in the construction of low-noise fiber lasers and the handling of mid-IR fiber. Additionally, you will have the opportunity to learn about single-cavity dual-comb sources and work at the forefront of mid-IR laser technology. This is an exciting opportunity to contribute to the advancement of this field of reasearch and ultimately make a meaningful impact on the detection of greenhouse gases.

   

  Who we are

  The research of the Optical Metrology Group (OMG) centers on optical metrology and sensing, ultimately aiming to develop experiments sensitive enough to track time variations of fundamental constants. To that end, we are working on novel schemes in broadband precision spectroscopy and light-matter interaction of structured light. Our research includes work on low-noise (mid-IR) fiber lasers, mid-IR supermirrors, environmentally stable single-cavity dual-combs, and frequency combs in general.

   

  What you will be doing

  • Work on some of the most advanced low-noise fiber oscillators in the near and mid infrared in state-of-the-art photonics laboratories
  • Analyze and interpret experimental data, and present results at group meetings
  • Collaborate with leading international research groups
  • Attend and present at national and international conferences and workshops
  • Work in the vibrant OMG and contribute to our overall success and growth
  • Train to become an independent researcher in the field of optical physics and photonics
