Abstract
A laser discharge, where the laser discharge 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.
Claims18
A laser discharge for use in discharge lasers comprising:
- at least one upper electrode, the upper electrode having a first surface;
- and
- at least one lower electrode, the lower electrode having a second surface,
- wherein the first surface and second surface are separated by at least one sidewall,
- wherein the first surface and the second surface face each other, portions of which are not completely covered by the at least one sidewall,
- wherein the first surface, second surface, and the at least one sidewall substantially fully surround the laser discharge, and
- wherein the discharge has a nonlinear shape including a plurality of parallel sections connected by at least one optical coupler.
