Abstract
A solid-state laser arrangement includes a plate-like solid body including a laser-active medium, a heat sink, a layer of adhesive between a carrier face of the heat sink and the plate-like solid body, and a reflective coating on a side of the plate-like solid body facing the adhesive layer, in which the adhesive layer is completely shielded from radiation from the plate-like solid body by a radiation-impermeable region between the side of the plate-like solid body facing the adhesive layer and the carrier face of the heat sink.
Claims17
A solid-state laser arrangement comprising:
- a plate-like solid body including a laser-active medium;
- a heat sink;
- an adhesive layer between a carrier face of the heat sink and the plate-like solid body, the adhesive layer terminating flush with a peripheral edge of the plate-like solid body along an edge of the adhesive layer, wherein both the peripheral edge of the plate-like solid body and the edge of the adhesive layer are inclined relative to the carrier face of the heat sink at the same, inclination angle (α) that is different from 90°;
- and
- a reflective coating on a side of the plate-like solid body facing the adhesive layer,
- wherein the adhesive layer is completely shielded from radiation from the plate-like solid body by a radiation-impermeable region between the side of the plate-like solid body facing the adhesive layer and the carrier face of the heat sink.
A method for producing a laser amplification arrangement, the method comprising:
- applying a reflective coating to a plate-like solid body;
- applying an adhesive layer between the plate-like solid body and a carrier face of a heat sink;
- forming an radiation-impermeable region between a side of the plate-like solid body facing the adhesive layer and the carrier face of the heat sink;
- and
- removing a portion of each of the plate-like solid body and the adhesive layer so that the adhesive layer terminates flush with the plate-like solid body, and so that a peripheral edge of the plate-like solid body forms an inclination angle (α) that is different from 90° with the side of the plate-like solid body facing the adhesive layer.
