The present invention relates to an optical fiber support and fixing device IM'f5 for supporting and fixing an optical fiber made of halide crystals such as halides, alkali halides, and thallium halides.

固定部３を右ｌノている。Explanation of leading wave 1fj Conventionally, the structure of the most well-known infrared optical transmission line is as follows.
In Fig. 1, a light beam (as shown in the cross-sectional view) has a fiber 1 (a light beam for transmitting light at its center) and a light beam for fixing this optical fiber 1 inside an optical fiber pipe 2. Turn the fiber fixing part 3 to the right.

ることはで゛き４Ｔい。In general, in order to match the position of the optical axis and the end face of the optical fiber to prevent light from entering the end face of the optical fiber with high efficiency, the input end of the optical fiber 1 is protected by protecting the optical fiber via the optical fiber fixing part 3. It must be fixed in place within the tube 2 by one notch. However, when silver halide crystal fibers or thallium halide crystal fibers are used for the optical fibers 1, as is well known, they are corroded by contact with other metals. It is not possible to use metals other than 4T for the optical fiber and fiber fixing portion 3 that come into contact with the optical fiber 1.

る。For this reason, in many cases, resin or ceramics have been used as the lug 1 used for the optical fiber fixing part 3. However, these monthly ratings generally reflect either a low IJ rating or poor thermal conductivity. When the melting point is low, when transmitting high-output light energy, for example, CO2 light 11, through an optical fiber, the input end of the optical fiber 1 is
The temperature of the optical fiber 7 and the fiber fixing part 3 rises due to the light dissipating and overlapping in the vicinity of 1, and as a result, the optical fiber fixing part 3 melts and damages the optical fiber 1. J: Tai! Even though the optical fiber fixing part 3 is formed using a material 1 having a melting point of 1, the temperature of the light 7 and im 1 itself increases due to its poor thermal conductivity, and as a result, the optical fiber 1 l[11fl is generated.

Ｃぞの中心軸線上に支持固定される。DESCRIPTION OF EMBODIMENTS FIG. 2 is a sectional view showing the structure of an optical energy transmission line according to the present invention. In the figure, the optical fiber 1G is made of halide crystals such as silver halide, alkali halide, and thallium halide, and the contact portion of the optical fiber identification part that comes into direct contact with this optical fiber 1G is made of fluorine resin.

散逸さけることができるからである。At the handle end described above, the heat-resistant polymer II9 such as fluororesin forming the first layer 4 transfers heat to the second layer 5 made of metal such as aluminum located on the outside thereof. It is desirable to make the thickness of the film as thin as possible, which is 1.1 mm, in order to improve the quality. In this case, by making the thickness thinner, the heat generated during the transmission of C1 optical energy can be efficiently dissipated to the second region 5 extending outward.
