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

Using light-beam scanning technology based on a potassium tantalate niobate (KTa1-xNbxO3, KTN) single crystal, we constructed a wavelength-swept light source for industrial applications. The KTN crystal is placed in an external cavity as an electro-o

Computed radiography (CR), which is one of the most useful methods for dental imaging and nondestructive testing, uses a phosphor imaging plate (IP) because it is flexible, reusable, and inexpensive. Conventional IP scanners utilize a galvanometer or

We have developed a highly stable electro-optic KTa1-xNbxO3 (KTN) deflector by enhancing electron transportation through KTN crystal. The amount of current is increased with 405-nm light irradiation to rapidly generate a stable refractive-index chang

A low-energy, high-repetition-rate picosecond laser (40 µJ, 20 kHz, 258 nm) was used for multiphoton ionization (MPI) in gas chromatography/time-of-flight mass spectrometry to quantitatively determine dioxins (DXNs) and polycyclic aromatic hydrocarb

Shaping the temporal profile of subterawatt optical pulses with a femtosecond duration is demonstrated with the help of a programmable pulse shaper, which is based on a liquid–crystal spatial light modulator. For safe operation, we place the pulse

The prevalence of undermasculinized external genitalia has increased in several countries including Japan, and this phenomenon has primarily been ascribed to the deleterious effects of environmental endocrine disruptors such as dioxins. To examine a
