Fabrication and characterization of Nd3+-oxyflouride laser glasses

Purpose active material is one of the important components of solid state laser. Solid state laser were called base on active material. That emit in specific wavelength. Target of this work is fabrication of laser glass as new host laser active material for achieving visible laser. Fabrication These glasses with composition in mol% of 42.5P2O5, 12Na2HPO4, 25CaF2, 15NaF, 5SiO2, 0.5Nd2O3 were prepared. These glasses were fabricated by heat melting method. Thermal properties of the glasses were investigated by thermal analysis. Absorption in infrared and visible range by Eclipse varion set were took. Up conversion luminescence measurement in the 1064 nm were performed with Nd:YAG laser and S100 spectrometer. Glass transition temperature 640oC and glass crystallization temperature 700oC were obtained. Absorption spectra indicate wavelength picks in 426, 496, 510, 525, 582, 746, 802 and 874 nm that are in agreement with those found in previous reports. According to the up conversion emission, the emission bands were achieved at 560, 620, 640nm. In the research work, fabrication of Nd3+ doped oxyfluorophosphate glasses was sucsesfull. In which observed upcoversion properties of infrared to visible range.
