Abstract

Many radicals spectroscopic signatures associated to gases of interest are in the 2.5 – 15 μm spectral range (4000-350 cm−1). This spectral range can be addressed by emissions from rare-earth ions embedded into chalcogenide glasses which are well-known for having low phonon energies [1]. We will show results concerning the development of an all-optical sensor at 4.4μm based on rare-earth doped chalcogenide glasses. The sensor schematic is presented in figure 1: a diode pumped Dy3+ doped chalcogenide fiber first produces the infrared signal, which is then sent to the gas cell to probe the gas absorption at 4.4 μm. The probe IR signal is then converted to 800nm by excited state absorption within a diode-pumped Er3+ doped chalcogenide fiber making possible to transport the probe signal through a silica optical fiber over large distances considerably increasing the scope of possible applications.
