Abstract
Abstract An RF-discharge waveguide laser incorporates two or more waveguides sharing a common set of discharge electrodes. The device may be used to provide two lasers operating on the same or different frequencies, or a single laser with two waveguides contributing to the power output.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
A waveguide laser system comprising: a ceramic member having a plurality of passages containing a gain medium fashioned therein; first and second electrodes disposed on opposite sides of said plurality of waveguide passages in said ceramic member for supplying power to said gain medium; means for resonating optical radiation in said gain medium; means for supplying radio-frequency power to said first and second electrodes so that each of said first and second electrodes supplies electromagnetic radiation to all of said plurality of passages.
Claim 2
Dependent Claim
83 words
A waveguide laser system comprising: a ceramic member having a plurality of passages containing a gain medium fashioned therein; first and second electrodes disposed on opposite sides of said plurality of waveguide passages in said ceramic member for supplying power to said gain medium; means for resonating optical radiation in said gain medium; means for supplying radio-frequency power to said first and second electrodes so that each of said first and second electrodes supplies electromagnetic radiation to all of said plurality of passages.
Claim 3
Dependent Claim
42 words
A laser system according to claim 1, in which said first and second waveguide passages are bounded by said means for resonating optical radiation in such a manner that radiation of different frequencies may be resonated in each of said waveguide passages.
Claim 4
Dependent Claim
37 words
A laser system according to claim 1, in which at least two of said plurality of waveguide passages are connected serially, whereby said at least two waveguide passages form a combined gain medium for a single laser.
