FIELD: fiber-optic technology; laser processing of materials.
SUBSTANCE: optical fiber is substituted with target when adjusting. Target is positioned at plane of entrance edge of optical fiber. Mark is applied onto surface of target by means of single laser pulse passed through focusing unit. Observing unit is installed. Plane of target is observed through eye-piece and focusing unit. Center of mark at target is put in coincidence with center -f cross-point of eye-piece due to tilting of observing unit by means of adjusting aid. Target is removed and fiber optic is placed instead of it. Focusing unit is tightly connected with optical fiber.
EFFECT: simplified design; improved reliability, improved precision; widened range of laser radiation wavelength into optical fiber.
