摘要： A connector for high energy beam is provided with a sleeve (43) fitted on an optical fiber (1a) and having an optical fiber support portion (43f) 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 a diameter of the optical fiber. Thus, a gap (43c,d) is formed around the optical fiber and in a proper length from the end face of the optical fiber, the optical fiber support portion being formed of a heat resistant inorganic substance of the melting point at a temperature of 1500°C or more, for example, a transparent substance, such as sapphire, or an opaque substance, such as aluminium oxide or the so-called fine ceramics. The connector of the invention constructed as above avoids burning, melting and diffusion of metallic material, and breakage of optical fiber when in use.
