Abstract
A gas ring-laser comprises a ceramic block containing a closed gas-filled channel (12) which extends along the sides of an equilateral triangle and forms a resonant cavity. An anode (64) and cathodes (76, 78) permit the creation of two gas discharges. With the aid of dielectric mirrors (26, 28 and 30), two light beams circulating in opposite directions are guided through the channel. In order to simplify construction, the ceramic block (10) consists of a glass ceramic which is produced from a green ceramic body by sintering. The mirrors (26, 28, 30) are located in adjustable metal holders (80, 82, 84) and fixed in the ceramic block (10) by means of glass solder (98). In addition, the other electrical connections for the electrodes in the cavity are sealed in place by glass solder. The invention also relates to a method for manufacturing such a gas ring-laser. The gas ring-laser may serve as an inertial sensor for measuring angular velocities by means of the Sagnac-effect.
