Abstract: A cavity-enhanced absorption spectroscopy instrument has an optical cavity with two or more cavity mirrors, one mirror of which having a hole or other aperture for injecting a light beam, and the same or another mirror of which being partially transmissive to allow exit of light to a detector. A spherical-spherical configuration with at least one astigmatic mirror or a spherical-cylindrical configuration where the spherical mirror could also be astigmatic prevents a reentrant condition wherein the injected beam would prematurely exit the cavity through the aperture. This combination substantially increases the number of passes of the injected beam through a sample volume for sensitive detection of chemical species even in less than ideal conditions including low power laser or LED sources, poor mirror reflectivity or detector noise at the wavelengths of interest, or cavity alignment issues such as vibration or temperature and pressure changes.

Abstract: Exemplary apparatus and method are provided. In particular, an electromagnetic radiation can be emitted with, e.g. a light source arrangement. For example, the light source arrangement can include a cavity and a filter, and a spectrum of the electromagnetic radiation can be controlled, e.g., with such cavity and filter, to have a mean frequency that changes (i) at an absolute rate that is greater than about 100 terahertz per millisecond, and (ii) over a range that is greater than about 10 terahertz. Additionally or alternatively, the light source arrangement can include a frequency shifting device which can shift the mean frequency of the electromagnetic radiation.

Abstract: A variable wavelength optical filter module according to the present invention includes a package, a variable wavelength optical filter, and a detector. The package includes a reflection part (reflecting faces) in the inside of the package. The variable wavelength optical filter is disposed in the inside of the package and includes a first reflecting plate and a second reflecting plate facing each other, with a clearance between the first reflecting plate and the second reflecting plate being variable. The detector is disposed in the inside of the package and detects a ray of light having passed through the variable wavelength optical filter. Then, the variable wavelength optical filter and the detector are disposed on the opposite side to the reflection part (reflecting faces). The ray of the light incident into the inside of the package via the variable wavelength optical filter enters the detector via the reflection part (reflecting faces).

Abstract: A photoelectric conversion element is realized in which the movement direction of electrons in the element changes according to the wavelength of light to be converted. A photoelectric conversion unit includes an active layer on which light to be converted is incident, an intermediate layer that is arranged on the active layer on a side opposite to the side on which the light to be converted is incident, and a reflection layer that is arranged so as to oppose the active layer with the intermediate layer interposed therebetween. The active layer includes a plasmonic material, which is a material in which plasmon resonance occurs due to a reciprocal action with the light to be converted. The intermediate layer has both a semiconductor property and transparency with respect to the light to be converted. The reflection layer has reflectivity with respect to the light to be converted.

Abstract: Optical spectroscopy system and method possessing spectral selectivity sufficient to distinguish isotopic line of the metal of interest. Each of the light beams, counter-propagating through vial with vapor of the sample, has been originated from the same light output of the laser source and modulated at a corresponding judiciously-determined frequency. The light-output, in turn, possesses a carrier frequency and two side-band frequencies defined with respect to a mean value of excitation frequencies of isotopes in the vapor.
