Cavity ringdown spectroscopy of thin films in the mid-infrared
Applied Optics, 2002To demonstrate the potential of the cavity ringdown technique in mid-infrared spectroscopy of thin film samples, we measured absorption losses in a C60 film on a BaF2 substrate using a tunable optical parametric amplifier source. With a Brewster angle sample geometry, we achieved a fractional loss sensitivity as small as 1.3 x 10(-7) with 1.5 cm(-1 ...

Spectroscopy on Vertical Microcavities for the Mid-Infrared
physica status solidi (a), 2001Mid-infrared microcavities from IV-VI semiconductors (lead salts) are investigated by infrared transmission measurements. Epitaxial Pb 1-x Eu x Te/EuTe multilayers with an refractive index contrast of more than 80% are used as Bragg interference mirrors with a very large mirror stop band width.

Characterization of Soils Using Photoacoustic Mid-Infrared Spectroscopy
Applied Spectroscopy, 2007This study investigates the use of photoacoustic spectroscopy (PAS) for rapid soil analysis. Photoacoustic spectroscopy requires very minimal sample preparation (air-drying), which is a major advantage compared to the more traditional transmittance technique, which requires time-consuming preparation of pellets.

Mid-Infrared Laser Applications in Spectroscopy
2007The vast majority of gaseous chemical substances exhibit fundamental vibrational absorption bands in the mid-infrared spectral region (≈ 2–25 µm), and the absorption of light by these fundamental bands provides a nearly universal means for their detection.

Mid-infrared spectroscopy for characterization of Baltic amber (succinite)
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2018Natural Baltic amber (succinite) is the most appreciated fossil resin of the rich cultural traditions dating back to prehistoric times. Its unequivocal identification is extremely important in many branches of science and trades including archeology, paleontology, chemistry and finally mineralogical and gemological societies.
