High-Power Laser Materials Processing: Applications, Diagnostics, and Systems X.
Structural monitoring during laser processing has recently been achieved with optical coherence tomography (OCT). Although a couple of industrial OCT monitoring systems have appeared, most are based on spectral-domain OCT, which uses an 800-nm band l

We developed a stable, compact, terahertz attenuated total reflected (ATR) spectrometer using an integrated prism, which unifies a terahertz emitter, a terahertz detector, and an ATR prism. Because the prism confines terahertz wave propagation within
