Abstract

The present invention provides an optical energy beam transmission path structure comprising at least one pair of optical fibers each having a connection end, and at least one fiber connector for connecting the connection ends of the paired fibers substantially coaxially. A small axial air gap is formed between the connection ends of the paired fibers, and an annular clearance is formed immediately around the connection end of the glass body of each fiber.
