Abstract
In a gas ring laser gyroscope characterized by a gain medium for producing at least one monochromatic narrow electromagnetic beam reflected to form a loop about the gain medium, the improvement wherein bypass channels are provided, displaced from the beam path, for reducing gas flow in the beam path. The bypass channels may extend about the gain medium and across the beam loop and may include controllable restrictions therein for selecting the flow rates therethrough.
Claims8
In a gas laser assembly characterized by a resonator cavity opening into a gain medium which is conformed to inject a laser beam into said resonator cavity and turning means disposed in said resonator cavity for returning said beam to said gain medium, the improvement comprising:
- a bypass tube connected across said gain medium for equalizing pressure differences at the ends thereof.
In a gas ring laser gyroscope characterized by a resonator cavity extending across a laser gain medium, said laser gain medium including at least two discharge paths formed across an anode and a cathode for injecting a first and a second oppositely directed beam into said resonator cavity, the improvement comprising:
- bypass means formed across said resonator cavity and across said gain medium for equalizing the pressures at the junctures thereof.
