The temperature dependence of the Raman scattering cross section of first and second order Stokes and anti Stokes Raman processes was discussed theoretically.

The fibre-optic preforms were produced, the fluoride fibers were fabricated, the anti-stokes fluorescence cooling mechanism was preliminarily researched.

Spectrum analysis by fluorescence spectrophotometerreveals that the materials appear to produce anti-stokes fluorescence peak with excitation sources atwavelengths longer than those corresponding to the peak of the luminescent bend.

In the process of experiment investigation on photonic crystal fiber fabricated by ourselves,by increasing the central wavelength of pump pulseλ_0 gradually,the frequency spectrum of pump pulse is widening gradually withλ_0 approaching toλ_D,at the same time,and the intensity of anti-Stokes wave is increasing gradually with the transform-efficiency being enhanced.

This paper, according to the sensibility of anti-stokes light to temperature, making use of many advantages of optical fiber communication, and matching with the electronic control and compensation circuit, designs the system of measuring temperature fields distributed optical fiber sensor for grain depot, the system can come true the stock of corps temperature s real-time controlli.
