Paper Abstract

One of the modern achievements of fiber optic technology is the development of IR (2-20 mm) optical fibers. Several types of such fibers are available now in the General Physics institute due to the works of groups, headed by V.G.Artjushenko and V.G.Plotnichenko . For IR fibers fabrication several materials such as chalcogenide and fluoride glasses, as well as thallium, silver and alkali-metal halide crystals are used. These are 0.3-1 mm diameter fibers with optical losses about 0.1-1 dB/m. Although this parameter is far from ideal it is possible now to use such fibers in diode laser spectroscopy having in mind the rapid technological progress. The main reason for this work was to make the first, experimental iteration to JR diode laser fiber optic spectrometer, to receive concrete experience in manufacturing and exploitation of this device. The present paper is the first short rcport about this work. The development of this device was based on previous experiments on coupling JR diode lasers and fibers1'2.
