Abstract:
1. A laser gain module comprising: a laser gain medium disposed along a central axis and adapted to produce stimulated emission of radiation at an emitted wavelength when pumped with a pump light wavelength; a first pump light reflecting surface disposed outside of the laser gain medium; a second pump light reflecting surface disposed outside of the laser gain medium, and symmetrically disposed around the central axis from the first pump light reflecting surface; a pump light chamber disposed between the laser gain medium and the first pump light reflecting surface along a pump light path portion of a closed internal pump light path within the laser gain module; the pump light chamber defined by the first and second pump light reflecting surfaces, and containing the pump light path portion and the laser gain medium; and a pump light plane of the laser gain module containing the central axis and on which the pump light enters the pump light chamber portion.
