Optical coherence tomography (OCT) 1, is an optical imaging modality which offers millimeter-depth volumetric optical biopsies of live biological samples within seconds 2,3. OCT identifies ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

High spatial resolution quantum sensing of near-surface nitrogen vacancy (NV) centers in diamond has enabled detection of magnetic, electrical, and thermal signals at the nanoscale. At depths of just ...

Non-destructive and accurate characterization of high aspect ratio (HAR) and composite micro-trenches is essential for semiconductor inspection in fields like microelectromechanical systems (MEMS) and ...
