ABSTRACT:
An optical chamber for use in a laser or other optical device includes a hollow container with holes at opposite ends. A fixed mirror is sealed to the housing and overlies one hole, whereas a movable mirror is sealed to the housing by a flexible seal such as an O-ring interposed between the mirror and the housing. A variable force actuator such as a piezoelectric element biases the movable mirror against the seal. By varying the force applied by the actuator, the movable mirror can be moved towards and away from the fixed mirror to vary the path length through the chamber. The chamber can provide a low cost tunable gas laser.
