By incorporating a length of single mode, polarization preserving fiber into the feedback loop of a modelocked color center laser (lambda = ~1.4-1.6 micron), we have created the first "soliton lase
We describe experimental discovery of a continuos down shift in the optical frequency of a soliton pulse as it travels along the fiber.
The NMR analyses of synthetic polymers in solution and in the solid state are now standard methods of characterization in most polymer chemistry laboratories.
AS professor of vocal physiology, Alexander Graham Bell did pioneer research in "devising methods of exhibiting the vibrations of sounds optically." In 1873, he became familiar with the phonautogra
Teleconference provides a convenient channel to conduct meetings with remote locations, increases productivity, and reduces the inconvenience of travel.
The frequency moments of a sequence containing m, elements of type i, for 1 - i - n, are the numbers F sub k = sum from n to i=1 m sup k sub i.
The function of the spacecraft antennas is to receive and transmit two distinct classes of signals: broadband microwave frequencies for communication service, such as television; and narrow-band V
This paper describes the communications repeater portion of the Telstar satellite.
The power supply .system used in the Telstar spacecraft employs a solar cell plant which converts solar radiation to electrical energy when the satellite is illuminated by the sun.
The radiation experiments 011 the T e l s t a r spacecraft were designed to measure the distribution in energy, position, and time of electrons and protons trapped in the earth's magnetic field in
