Abstract: Provided is a device/method of alignment of a laser's beam with the laser's support system so that the beam is substantially parallel in a chosen direction with respect to a reference line on the laser's support system.

Abstract: Certain example embodiments of this invention relate to waveguide lasers (e.g., RF-excited waveguide lasers). Certain example embodiments of this invention provide combined waveguide cover and non-coupled top electrodes, and/or heat load balancing vacuum vessels including multiple (e.g., two or more) chambers. In certain example embodiments, RF energy may couple through the combined waveguide cover and non-coupled top electrode without significantly traversing the insulating carrier material via one or more cutouts or gaps formed in the RF coupling region of the top (or even a bottom) electrode. In certain example embodiments, first and second chambers of the vacuum vessel may be arranged so that heat generated in the discharge region flows away from the first and second chambers, thereby reducing thermally induced distortion of the optical component during laser operation. These techniques may be used alone or in various combinations.

Abstract: A laser waveguide, where the laser waveguide can be formed by electrodes and at least one sidewall in a manner allowing a more compact structure than previously provided. Protrusions in the electrodes allow easier laser starts, and sectional sidewall(s) allow easier fabrication of sidewall(s), decreasing manufacturing costs.
