Plasma resonance enhancement of Raman scattering by pyridine adsorbed on silver or gold sol particles of size comparable to the excitation wavelength

, 1979
Intense Raman scattering by pyridine molecules adsorbed on silver or gold aqueous sol particles of dimensions comparable to the wavelength is reported. The degree of intensity enhancement is strongly dependent on the excitation wavelength, with a sharp ...

Wavelength Division Multiplexers and the Measurement of the Channel Wavelengths

1995
In the first part in the paper, we review different WDM integrated optics devices: in lithium niobate, on glass, on silicon or InP subtrates. It is shown that the main problem to be solved, in most of the cases, is the wavelength and transmission sensitivity to polarisation.

Two-Wavelength Interferometry

Applied Optics, 1973
Previous methods of two-wavelength variable-sensitivity interferometry are reviewed and a simplified two-wavelength technique for interferometric testing under static conditions is discussed. An extension of the static technique to real-time dynamic testing is proposed and an operational variable-sensitivity interferometer utilizing the real-time ...

On the right wavelength

Physics Bulletin, 1988
The electromagnetic radiation spectrum has long been subdivided into a series of bands (such as infrared or ultraviolet) because these have a useful descriptive value regarding the physical attributes of a particular range of wavelengths or frequencies.

A Wavelength Meter

1977
Two years ago we set out to design and build a wavelength meter [1] that would complement our tunable source research. [2] The design goals were a device that measured wavelengths for both pulsed and cw lasers, displayed single pulse laser bandwidths, used inexpensive broadband optics and could be interfaced with a minicomputer.
