Novel Applications of QCL Frequency Combs
-
Dual-Comb Spectroscopy
Dual-comb spectroscopy performed in the mid-infrared offers the promise of high spectral resolution with very short acquisition times.
-
THz Imaging
QCL frequency combs emitting THz radiation have been used for imaging applications. This non-ionising radiation is ideal for in-vivo imaging.
-
QCL Comb Metrology
QCL combs have equidistant peaks in their emission spectra and low noise, providing useful references for the study of measurement (metrology).
