Abstract
An investigation has been carried out into the use of two crystals of the olivine family, forsterite and olivine, CrMg2SiO4 and Cr:(Mg,Fe) S iO4, respectively, in optical fiber fluorescence thermometry. The resu lts show that the Cr3+-based emission in the near-infrared is dominant under pumping with light from a red diode laser, and a useful sensor performance in the 200 degrees region around room temperature is seen using probes constructed from these materials.
