Patent ID: 8639071

Claim:
An apparatus for forming laser radiation, wherein the apparatus can form the laser radiation such that the laser radiation can enter an optical fiber, the apparatus comprising: a component; a first lens device for at least one of deflection, imaging or collimation of the laser radiation with respect to a first direction, said first lens device imaging the laser radiation on an inlet area of the optical fiber; and a second lens device for at least one of deflection, imaging or collimation of the laser radiation with respect to a second direction, said second lens device imaging the laser radiation on the inlet area of the optical fiber, said first and second lens devices being disposed in or on said component; wherein the apparatus can be used to form laser beams which originate from a laser diode bar or a stack of laser diode bars, wherein the first direction corresponds to a fast axis, and the second direction corresponds to a slow axis; wherein said first lens device as at least one first cylindrical lens; and wherein said second lens device is an array of second cylindrical lenses.
