Nanoscale displacement sensing based on nonlinear frequency mixing in quantum cascade lasers
F. P. Mezzapesa, L. L. Columbo, G. De Risi +4
We demonstrate a sensor scheme for nanoscale target displacement that relies on a single Quantum Cascade Laser (QCL) subject to optical feedback. The system combines the inherent s…
