3-year postdoc / scientist position in the field of mid-IR frequency comb spectroscopy

Within this interdisciplinary project, we will develop high-precision, mid-IR dual-comb spectroscopy based on quantum cascade lasers (QCLs) to investigate control strategies for emerging ultrafast laser manufacturing processes. We thus take advantage of the unique speed and spectral coverage of QCL frequency combs, and of very recent developments in laser driving, data acquisition and analysis. The work involves intensive collaboration with experts in laser manufacturing, operando analysis and QCL design at EPFL, PSI and ETHZ.

Job description, responsibilities and tasks:

• Develop a heterodyne (dual-comb) spectrometer for real-time measurements of changes in mid-IR spectral features during ultrafast laser processing of materials.
• Design the optical layout, detection scheme, and data processing hardware architecture.
• Investigate and implement fast data retrieval and processing algorithms to provide feedback for closed-loop manufacturing control.
• Coordinate research with EPFL (laser manufacturing), PSI (imaging) and ETHZ (QCL development).
• Lead and contribute to writing of peer-reviewed publications and promote the results at international conferences.
