FIELD: optics.
SUBSTANCE: invention relates to fibre-optic equipment and is intended for use in creation of remote electric power sources based on light guides, laser medical apparatuses and other unit, and apparatuses utilising systems for transmitting laser emission through a light guide. Claimed is a method for introducing powerful multimode pulse laser emission into a light guide, wherein a laser, a lens and a light guide secured in an adjusting apparatus wherein a converging laser emission beam is formed using a lens, are used, installed sequentially on the same optical axis and optically connected. The light guide is located in the focus of the lens, and when the adjustment apparatus is used, the end of the light guide is placed in the area of the focal spot of laser emission created by the lens. By glass dividing plates installed along the course of propagation of the laser beam and by a mirror installed after all of the glass plates, the laser emission is divided into equal parts, each of the parts is focused by the lenses and introduced into intermediate light guides through focons, and all intermediate light guides further combined into one used to transmit the laser emission. The ends of the focons are therein placed in the area of the focal spots of laser emission, created by the lenses using the adjusting apparatuses for securing focons.
EFFECT: increase in the reliability of introducing powerful multimode pulse laser emission into a light guide.
