FRM team member Christina Hofer was invited to present our paper “Mid-infrared electric field sampling approaching single-photon sensitivity”  at the EUROPHOTON conference (https://www.europhoton.org/).
We present a Thulium-fiber-laser-based, field-resolved spectrometer, optimized for mid-infrared photon detection efficiency. With this system, we measure few-cycle mid-infrared fields with nearly single-photon sensitivity via electro-optic sampling. This pushes field-resolved spectroscopy to its fundamental limits and paves the way for linear detection of mid-infrared intensities over 18 orders of magnitude.
The talk will be given online, on Thursday, September 3rd, at 13:30
