Laser and Quantum Radiometry

Working Group 4.54

Profile

The working group Laser and Quantum radiometry is responsible for the dissemination of radiometric units in the field of laser radiometry for the wavelength range between 193 nm and 10.6 µm. It carries our out research and development for detectors for laser radiometry as primary, secondary and transfer standards.

Furthermore, the working group conducts research for the realization of efficient single-photon sources for radiometric and quantum metrological applications and it characterizes single-photon detectors.
