    Abstract: A gas-discharge waveguide CO2 laser has a Z-shaped folded waveguide formed by three ceramic tubes. Ends of the adjacent tubes are shaped and fitted together to form a common aperture. The tubes are held fitted together by spaced-apart parallel discharge electrodes. Four mirrors are arranged to form a laser-resonator having a longitudinal axis extending through the tubes.

    Abstract: The apparatus of the present invention significantly improves the optical intensity induced damage limit of optical quality crystals, and in particular crystals used in the conversion of laser radiation at a specific wavelength to another wavelength or other wavelengths through non-linear interaction of the input laser radiation with the optical crystal medium. In accordance with the present invention, passive optical elements are positioned at the laser beam exiting and entrance surfaces of the active optical element. The surfaces of the passive optical elements are placed up against respective exiting and entrance surfaces of the active optical element. Since the optically transparent passive optical elements have higher mass than optical coatings, they provide vastly superior cooling, and therefore, considerably higher laser damage threshold for the surfaces. Higher damage thresholds results in a significant increase in the performance, reliability, and failure damage safety margin while reducing size and cost of high intensity laser systems and subsystems that utilize active optical elements.

    Abstract: A CO2 laser has a resonator mirror that oscillates about an axis perpendicular to the resonator axis through an angular range of oscillation sufficient that the resonator is only able to deliver radiation for a fraction of an oscillation period of the mirror. In one example of the laser, the oscillating mirror is an end-mirror of the resonator. In another example, the oscillating mirror is a fold mirror of the resonator.

    Abstract: A slab laser includes two elongated electrodes arranged spaced apart and face-to-face. Either one or two slabs of a solid dielectric material extend along the length of the electrodes between the electrodes. A discharge gap is formed either between one of the electrodes and one dielectric slab, or between two dielectric slabs. The discharge gap is filled with lasing gas. A pair of mirrors is configured and arranged to define a laser resonator extending through the gap. An RF potential is applied across the electrodes creating a gas discharge in the gap, and causing laser radiation to circulate in the resonator. Inserting dielectric material between the electrodes increases the resistance-capacitance (RC) time constant of the discharge structure compared with the RC time constant in the absence of dielectric material. This hinders the formation of arcs in the discharge, which enables the laser to operate with higher excitation power, higher lasing gas pressure, and higher output power than would be possible without the dielectric inserts.

    Abstract: A communications transmission system and method modulates a radiation source at higher rates for either fiber optic telecommunication systems or for digital electrical or optical switches associated with computer routers or servers. A first source provides a carrier signal; a modulator receives the carrier signal and an information signal to generate a modulated carrier signal. A second source provides a transmission signal; and a signal mixer receives the modulated carrier signal and the transmission signal to generate a frequency shifted transmission signal. The transmission system increases the amount of analog or digital information that can be transmitted over a communications network. The modulated carrier signal and the frequency shifted transmission signal may be filtered.

    Abstract: A gas includes a housing having a symmetrical arrangement of upper and lower cooling members for removing heat generated in a gas-discharge excited by an electrode assembly. The electrode assembly is clamped between the cooling members and is itself essentially symmetrically arranged. The cooling members and the electrode assembly are mechanically isolated in the housing by a surrounding diaphragm-like arrangement that connects the cooling members to side-walls of the housing. An RF power-supply for supplying the electrode assembly is mounted on one of the sidewalls to avoid disturbing the symmetry of the cooling and electrode arrangements.
