Abstract
Embodiments of silicon-based thermal energy transfer apparatus for a gain medium of a laser system are provided. In one aspect, a silicon-based thermal energy transfer apparatus includes silicon-based first and second manifolds each having internal coolant flow channels therein. When the first and second manifolds are coupled together, a first groove on the first manifold and a second groove on the second manifold form a through hole configured to receive the gain medium therein. The through hole has a polygonal cross section when viewed along a longitudinal axis of the gain medium.

A thermal energy transfer apparatus that removes thermal energy from a gain medium of a laser system, the apparatus comprising:
- a silicon-based first manifold having first internal coolant flow channels therein, the first manifold having a first primary side and a second primary side opposite the first primary side with the first internal coolant flow channels fluidly connect the first primary side and the second primary side of the first manifold, the second primary side of the first manifold having a first groove;
- and
- a silicon-based second manifold having second internal coolant flow channels therein, the second manifold having a first primary side and a second primary side opposite the first primary side with the second internal coolant flow channels fluidly connecting the first primary side and the second primary side of the second manifold, the second primary side of the second manifold having a second groove, wherein:
- when the first manifold and the second manifold are coupled together with the second primary side of the first manifold facing the second primary side of the second manifold, a first through hole configured to receive the gain medium is formed between the first manifold and the second manifold, and
- the first through hole has a polygonal cross section when viewed along a longitudinal axis of the gain medium.
