Patent ID: 8824519

Claim:
A fiber optic pump module comprising: an optical emitter including a plurality of VCSEL devices, said optical emitter supported on a thermal mount; one or more optical components, said optical components disposed at a predetermined distance following said emitter to collimate respective optical beam emitted from the plurality of VCSEL devices, such that a combined optical beam has a substantially uniform intensity; an optical coupling device disposed at a pre-determined distance following the one or more optical components; an optical fiber secured in a fiber alignment housing, said optical fiber having an input end positioned at a pre-determined distance following said optical coupling device, such that the optical coupling device and said input end of the optical fiber are coaxially aligned with the combined optical beam for effective coupling of a maximum intensity of the combined optical beam focused on the input end of the optical fiber to provide an output pump beam at an output end of the optical fiber; an external housing, said housing having a thermally conducting base plate in thermal contact with the optical emitter, and wherein the optical emitter, the one or more optical components, the optical coupling device, and the fiber alignment housing are secured coaxially on the base plate; and an external elevated cover, said cover to enclose the fiber optic pump module on the base plate, wherein said cover further includes a fiber alignment guide and a bend radius limiter on one end to support and secure the optical fiber coming out of the external housing, and wherein said external housing is adaptable for an external cooling device placed in thermal contact with the base plate using a circulating fluid that is one selected from the group consisting of a gas, a liquid and a combination thereof.
