Karl Bertling

Dr. Karl Bertling has made significant contributions to pioneering imaging and sensing via laser feedback interferometry, spanning diverse laser technologies including sensors based on visible lasers, infrared surface-emitting lasers, mid-infrared inter-band cascade lasers, and terahertz quantum cascade lasers. His current research focus includes leveraging terahertz quantum cascade laser feedback interferometry for early melanoma detection and agri-photonics, as well as near-field terahertz and mid-infrared imaging of nanomaterials and nanostructures.
