CO2 laser lab
ETRO Infrastructure

Welcome to ETRO's CO2 laser laboratory, where we study novel semiconductor based electro-optic devices, teach students how to operate the laser to characterize their own developed detectors and investigate laser-material interaction. This laboratory is equipped with high-end sealed and non-sealed CO2 lasers, a precise motion control system, dedicated measurement / peripheral equipment and a fume extraction system. The lab is mainly used for research and education, but recent industrially oriented projects opens doors towards laser applications in the context of rapid-prototyping.

Relevant Laser equipment

  • 2x Sealed-off Millennium CO2 laser - CW power: 50 W.
  • 1x Edinburg CO2 laser - CW power: 50 W.
  • 1x Pulsed CO2 laser - pulse length: 150 ns / pulse energy: few mJ.

Research & expertise

One may wonder what a laser laboratory has to do with the electronics and informatics department (ETRO) of the Faculty of Engineering. The variety of CO2 lasers available in this lab are used as a tool to characterize novel electro-optic components, developed at ETRO within Prof. Stiens's group. More precisely our domain of expertise is found in the field of:

  • Semiconductor based devices: design and fabrication of thermo-electric photodetectors for high power CO2 lasers & modulators / Q-switches for CO2 lasers.
  • CO2 laser resonator design and alignment

Education Related Lab Activities

Students that follow the course "Technological Processes for Photonics and Electronics: laboratory" of Prof. Stiens are given the opportunity to work with these lasers in order to test detectors that they fabricated based on gathered technological knowledge, and to investigate laser based processes (e.g. laser engraving in PMMA).
