Abstract
A compact laser in accordance with an exemplary embodiment in the present disclosure includes a compact resonator structure using a non-planar resonator geometry of bulk components. The laser further includes a laser gain medium and a pump source integrated within an optical path of the resonator. Some embodiments contain modifications to the resonator structure for integration of the laser gain medium, for controlling the output from the laser, and/or for controlling the physical and operational parameters of the laser. Some embodiments contain modifications to the laser gain medium or other bulk components of the resonator to integrate these bulk components within the resonator structure.

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.
A laser gain module comprising:
- a plurality of bodies assembled to create a closed internal pump light path within a pump light chamber lying in a pump light plane including a laser gain medium along a central axis within the pump light plane and adapted to produce stimulated emission of radiation at an emitted wavelength when pumped with a pump light wavelength;
- a first pump light chamber portion lying in the pump light plane containing the closed internal pump light path between the laser gain medium that is flanked on a first side by a first mirror body of the plurality of bodies;
- a second pump light chamber portion lying in the pump light plane containing the closed internal pump light path between the laser gain medium that is flanked on a second side by a second mirror body of the plurality of bodies;
- the first mirror body defining a first interface between a first pump light path and a second pump light path;
- and
- the second mirror body defining a second interface between the second pump light path and a third pump light path;
- wherein the closed internal pump light path is contained entirely in the first pump light chamber portion, the second pump light chamber portion, and the laser gain medium.
