our latest field-resolved infrared spectrometer (1)

Infrasampler 3.0 is our latest field-resolved infrared spectrometer. It uses the carrier-envelope-stable single-cycle output from a Cr:ZnS oscillator to generate infrared pulses simultaneously covering a two-octave-spanning spectral range from 3 to 12 mm. We use these pulses to excite blood-plasma samples and measure the electric response field with electro-optic sampling. Using two synchronized laser oscillators with attosecond-precision delay calibration, we record reproducibly 4000 measurement scans per second. An automated high-throughput sample handling system allows us to perform in future comparison measurements on large numbers of blood plasma samples. Our current system will be transferred to the new CMF laboratory at the ELI ALPS in Szeged, Hungary, where it will be used to measure samples from the Health4Hungary campaign (link). The goal is to understand if infrared molecular fingerprinting can provide a standard approach for personalized health monitoring based on regular blood analysis.
