Abstract: PROBLEM TO BE SOLVED: To obtain a non-relayed optical transmission system having a more high efficiency/economical property and a non-relayed optical transmission method. SOLUTION: The non-relayed optical transmission system has a non-relayed transmission line having pure silica core fibers 4 and dispersion compensating fibers 5 to form a non-relayed transmission section 10 for propagating optical signals without relaying.

The attenuated signal is amplified e.g. by a laser beam of 1.48 μm incident from behind to expand the non-relay transmission range. Using the dispersion compensating fibers in the non-relay transmission section, a long range and large capacity transmission is performed without using any relay to eliminate the need of signal amplifications, etc., at the terminal.

Title: Plasma focused high energy photon source
Inventor: PARTLO WILLIAM N
IPC: G03F7/20
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To make it possible to work at a high repeat speed and generate high-energy ultraviolet rays and X-ray radiation by installing a pair of plasma pinch electrodes in a vacuum chamber including a working gas. SOLUTION: Since a small amount of a working gas such as a mixture of helium and lithium steam exists near a base of coaxial electrodes 8 to which electricity is supplied by a low-inductance pulse power circuit 10, avalanche breakdown occurs between inside and outside electrodes of the electrodes 8 whenever a high-voltage pulse is applied, the gas is ionized and conductive plasma is generated between the electrodes. Then, current flows from the inside electrode to the outside electrode to generate a magnetic field, which accelerates a fluid charge carrier and moves it away from the base of the electrodes 8. When the plasma reaches a tip of a central electrode, the force of an electric field and a magnetic field pinches the plasma along the center line of the central electrode and rapidly raises the pressure and temperature of the plasma to reach an extremely high temperature.
