Abstract:
A lasing medium having a tailored dopant concentration and a method of fabrication thereof is disclosed. The lasing medium has a single crystal having a continuous body having a selected length, wherein the crystal comprises dopant distributed along the length of the body to define a dopant concentration profile. In one embodiment, the dopant concentration profile results in a uniform heating profile. A method of fabricating a laser crystal having a tailored dopant concentration profile includes arranging a plurality of polycrystalline segments together to form an ingot, the polycrystalline segments each having dopant distributed, providing a crystal seed at a first end of the ingot, and moving a heating element along the ingot starting from the first end to a second end of the ingot, the moving heating element creating a moving molten region within the ingot while passing therealong.

Claim (Index 1):
A method comprising:\n determining a target dopant concentration profile of a laser crystal; arranging multiple polycrystalline segments together in an order to form an ingot, each segment having dopant distributed therein, each segment having a different dopant concentration than other segments, the order based on decreasing dopant concentration such that the segment at a first end of the ingot has a higher dopant concentration and the segment at a second end of the ingot has a lower dopant concentration; providing a seed crystal at the first end of the ingot; and moving a heating element along the ingot from the first end to the second end so as to create a single laser crystal having the target dopant concentration profile, the target dopant concentration profile changing smoothly and continuously from the first end to the second end, the moving heating element creating a moving molten region within the ingot while passing therealong, the heating element moved so as to create the moving molten region with a predetermined length, the predetermined length selected to result in the target dopant concentration profile.
