Abstract
A connector for a high energy beam, which is provided with a sleeve fitted on an optical fiber and having an optical fiber support portion of an inner diameter about equal to a diameter of the optical fiber and a larger diameter portion positioned ahead of the optical fiber support portion and having an inner diameter larger than the diameter of the optical fiber so as to form a gap around the optical fiber and in a proper length from the end face of the optical fiber. The optical fiber support portion is formed of a heat resistant inorganic substance having a melting point of 1500.degree. C. or more, for example, a transparent substance, such as sapphire, or an opaque substance, such as aluminium oxide; the so-called fine ceramics. The connector of the present invention is free from burning, melting and diffusion of metallic material, and breakage of optical fiber when in use, thereby being easy to handle and high in quality and reliability and having a long life time.
