Abstract
A laser component is provided, including a laser medium and a transparent heat transmitting member, at least one of which is oxide. Bonding surfaces of the laser medium and the transparent heat transmitting member are exposed to oxygen plasma, and thereafter the bonding surfaces are brought into contact without heating. The laser medium and the transparent heat transmitting member are bonded at atomic levels, their thermal resistance is low, and no large residual stress is generated due to the bonding taking place under normal temperature. The process of oxygen plasma exposure ensures transparency of their bonding interface. The laser medium and the transparent heat transmitting member are stably bond via an amorphous layer.
Claims21
A method of manufacturing a laser component that bonds a laser medium and a transparent heat transmitting member, wherein at least one of the laser medium and the transparent heat transmitting member is oxide, the method comprising:
- exposing both of bonding surfaces of the laser medium and the transparent heat transmitting member to oxygen plasma;
- radiating inert gas atomic beam to both of the bonding surfaces in vacuum after the exposing;
- and
- bringing the bonding surfaces into contact after the radiating.
A laser component comprising a laser medium and a transparent heat transmitting member, wherein
- at least one of the laser medium and the transparent heat transmitting member is oxide,
