Patent ID: 7941018

Claim:
A system for transmitting laser beams, comprising: a laser beam source; a first lens assembly operably coupled to the source, the first lens assembly causing the laser beam to converge from a larger diameter at an outlet of the first lens assembly to a smaller diameter; a first optically transmissive block operably coupled to the first lens assembly and have flat inlet and outlet ends for receiving the laser beam, the first optically transmissive block causing the laser beam to continue converging to a smaller diameter at an outlet of the first optically transmissive block; an inlet end of an optical fiber physically abutting and coupled to the outlet end of the first optically transmissive block; a second optically transmissive block having flat inlet and outlet ends, the inlet end of the second optically transmissive block being in physical abutment with and coupled to the an outlet end of the optical fiber, the second optically transmissive block causing the laser beam to diverge from a smaller diameter at the inlet end of the second optically transmissive block to a larger diameter at the outlet end of the second optically transmissive block; wherein a diameter of the first optically transmissive block and a diameter of the second optically transmissive block are each significantly larger than a diameter of the first optical fiber; and a second lens assembly operably coupled to the outlet end of second optically transmissive block, the second lens assembly directing the laser beam from to a target.
