Abstract:
An optical system, comprising:a diode laser having an active area substantially elongated along and parallel to a slow axis of said diode laser, said active area configured to emit an optical beam; a fast axis collimation lens configured to collimate a fast axis of said optical beam; and an optical beam inverting array comprising a planar grin lens array and including a plurality of individual array elements aligned such that said optical beam is cut into more than two individual beam sections, said optical beam inverting array configured such that said beam sections propagate through said individual array elements, each of said individual array elements imaging said individual optical beam sections with a magnification M of substantially M=âˆ’1, wherein planes of equal refractive index in said planar grin lens array are aligned at an angle of substantially Â±45Â° with respect to a plane defined by a propagation direction of said optical beam and said slow axis of the diode laser.
