Chalcogenide Glass Fibers for Analytical Mid-IR Spectroscopy of Oil Products and Environmental Objects

V.S. Shiryaev E.V. Karaksina Т.V. Kotereva А.P. Velmuzhov Б.С. Степанов

In this paper, recent experimental results on the development of high-purity passive and active chalcogenide glasses and fibers for mid-IR fiber evanescent wave spectroscopy (FEWS) are presented. The high purity Ge-Se(-I), Ge-Sb-Se, Ge-As-Se-Te, and REE-doped Ga(In)-Ge-As(Sb)-Se glasses were prepared and studied. On the base of chalcogenide glass fibers, the sensor setup for studying the elemental composition of liquids by the method of evanescent spectroscopy was developed and created. To increase the sensitivity of FEWS sensors, novel types of chalcogenide fiber sensor probes were developed. Successful tests of different passive chalcogenide fibers as FEWS sensors and active doped fibers as luminescent middle infrared sources to determine the elemental composition of oil products and environmental objects were carried out.

Mid-IR luminescence of Cr²⁺: II — VI crystals in chalcogenide glass fibres

Quantum Electronics (2010)

Р. А. Миронов E.V. Karaksina A O Zabezhailov R M Shapashnikov М. Ф. Чурбанов

Optical fibres have been fabricated for the first time from As2S3 glass containing chromium-doped ZnS and ZnSe crystals, and their optical loss and luminescence spectra have been measured in the mid-IR. In the spectral range 2 — 3 μm, the optical loss in the fibres is 2 — 4 dB m-1. The fibres have a broad luminescence band in the range 1.8 — 3 μm, with a maximum near 1.9 μm, which is due to Cr2+ 5E — 5T2 intracentre transitions in the II - VI host.
