摘要： A laser and methods for providing a continuous wave output beam. The laser and method includes positioning a micro-plasma chip capable of creating micro-plasmas within a resonant cavity. A gas is input into the resonant cavity and flows around the micro-plasma chip. Micro-plasmas ignite and excite the gas to create metastables. The metastables are further excited by an optical pump having an energy sufficient to cause the metastables to lase.

摘要： A continuous-wave (CW), ultraviolet triply-optically-pumped atomic laser (TOPAL) is disclosed. The inventive laser device includes a laser active media comprising a mixture of a neutral atomic vapor and one or more buffer gases. The gain mixture is placed within a segmented gain cell, allowing for periodic, selected spectral filtering of deleterious ASE transitions; the segmented gain cell, in turn, is placed within an optical cavity with a high Q at a specified ultraviolet wavelength, and is successively, resonantly excited by three drive pump lasers, in three energy-contiguous visible/IR electric-dipole allowed transitions, producing a steady-state electron population inversion density between a high-lying electronic energy level and the ground electronic level, and producing laser emission on a UV transition (within the spectral range ˜230 to ˜370 nm) terminating on the ground electronic level.

摘要： An LPP EUV light source is disclosed having an optic positioned in the plasma chamber for reflecting EUV light generated therein and a laser input window. For this aspect, the EUV light source may be configured to expose the optic to a gaseous etchant pressure for optic cleaning while the window is exposed to a lower gaseous etchant pressure to avoid window coating deterioration. In another aspect, an EUV light source may comprise a target material positionable along a beam path to participate in a first interaction with light on the beam path; an optical amplifier; and at least one optic directing photons scattered from the first interaction into the optical amplifier to produce a laser beam on the beam path for a subsequent interaction with the target material to produce an EUV light emitting plasma.

摘要： A discrete hybrid amplifier is disclosed for use in optical fiber systems. The amplifier uses one or more Raman laser pumps together with semiconductor optical amplifiers in series to produce a relatively level gain across the frequency range of interest. The Raman pump utilizes a length of highly non-linear fiber as the gain medium. The disclosed lower-cost hybrid amplifier is especially useful in coarse wavelength division multiplexing (CWDM) systems and in local access portions of the network.

摘要： A gas laser oscillator of easy maintenance which is capable of switching a beam mode at high speed. Electric discharge sections in which gas medium is flown are formed in an optical resonating space in an electric discharge tube between a rear mirror and an output mirror. Electrodes are connected to electric discharge power sources (alternating current or direct current power sources). Coils are wound around the electric discharge tube at the respective electric discharge sections and excited by coil excitation circuits. Directions and intensities of the excitation currents from the coil excitation circuits are controlled by a controller. Regions in which the electric discharge currents flow between the electrodes in the respective electric discharge sections are varied by magnetic fields generated by the coils in accordance with the directions and intensities of the excitation currents of the coils, to thereby control the beam mode.
