Femtolab
FemtoLab is a laser spectroscopy and communications laboratory in the physics department at Stevens Institute of Technology, Hoboken, New Jersey The lab's director is Rainer Martini. The main focus of the research in this laboratory is the development of new devices and application in the infrared region of the spectrum. A specific focus is thereby on security as well as communication application. Research In a long term study the laboratory compares since 2001 atmospheric propagation at different wavelengths in indoor and outdoor studies to find the optimal wavelength for free-space optical communication. It uses a quantum cascade laser to transmit data using the mid-infrared part of the spectrum, which propagates much more favorably under bad weather conditions like fog. A secondary focus of research is based on the component development for the far-infrared spectral region, the so-called Terahertz radiation, terahertz spectrum. Components include modulators and lenses, and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structu ...
