Abstract
A total-internal-reflection thermally compensated rod laser including a lasing rod composed of crystalline or glass material doped with at least one lasing ion. The rod has an optical axis, an axially extending, substantially optically flat, exterior surface, and a substantially optically flat conical surface at each end. Both conical end surfaces are coaxial with the optical axis and has a truncated tip. The first end has a convex surface and the second end has a concave surface. The rod has a geometry, including a diameter and a length, selected to provide substantially no net depolarization of an incident beam.
