<p>An electrode and getter structure (37) for a ring laser gyroscope (10) that includes a frame (12) having a cavity (26) therein that contains a gain medium (55) and an electrode bore (40) extending from a surface (42) of the frame (12) to the cavity (26) includes a metalization layer (4') formed on the surface (42) of the frame (12). The metalization layer (44) includes an electrode (52) that is adjacent the electrode bore (40). A getter well (64) is sealed to the metalization layer (44) around the electrode bore (40), and a getter (72) is mounted in the getter well (64) spaced apart from the frame (12). The getter well (64) preferably is a hollow glass cylinder (63) having a closed end (66) and an open end (68) mounted to the metalization layer (44). A spring (46) preferably is retained in the getter well (64) by elastic forces in the spring (46) with the getter (72) being attached to the spring (46) and aligned with the electrode bore (40).</p> |
