Abstract
There is provided a laser system having a cylindrically-shaped annular mirror with at least one opening in its surface; a pair of planar metallic electrodes disposed proximate opposite edges of the annular mirror, normal to the axis of the annular mirror, the electrodes configured to have an RF field applied between them; a pair of end mirrors disposed at said at least one opening; and a ceramic material in the form of a disc, disposed in the internal volume of the annular mirror, the ceramic material having a series of channels formed therein such that they generate a zig-zag pathway in the ceramic material, wherein (i) the zig-zag path, when filled with a gain medium, (ii) the annular mirror and (iii) the pair of end mirrors, together constitute a laser cavity.
Claims20
A system comprising:
- an annularly-shaped mirror whose inner surface has a high reflectivity at the wavelength at which said laser system is intended to lase, said annularly-shaped mirror having at least one opening in its surface;
- a pair of planar metallic electrodes disposed proximate opposite edges of said annularly-shaped mirror, normal to the axis of said annularly-shaped mirror, said electrodes configured to have an RF field applied between them;
- a pair of end mirrors disposed at said at least one opening, one of said end mirrors being a high reflectivity mirror, and the other of said end mirrors being a partial reflector;
- and
- a ceramic material in the form of a disc, disposed in the internal volume of said annularly-shaped mirror, said ceramic material having a series of channels formed therein such that they generate a zig-zag pathway in the ceramic material, each leg of said zig-zag path being aligned at an angle such that said leg does not pass through the axis of said annularly-shaped mirror, and meets said annularly-shaped mirror at a different pair of points around the circumference of said annularly-shaped mirror,
- wherein;
- said channels are adapted to contain a gain medium, and
- wherein (i) said zig-zag path, (ii) said annularly-shaped mirror and (iii) said pair of end mirrors, together constitute a resonant cavity.
