## Abstract Doping possibility of long ruby crystals grown by Czochralski method under reducing protective atmosphere by iron ions in described. Using the admixture of hydrocarbons to the protective atmosphere this dopage may be realized. Iron ions increases damage threshold of the Qβswitched laser

This paper presents the results obtained on measuring the apparent activation energies of hardening reactions in unsaturated polyesters running on using various monosubstituted and l,l'-disubstituted ferrocene derivatives as accelerators. It has been found that the apparent activation energies of th
The Role of Iron Ions in YAG and YAP Dedicated to Professor Hermann Neels on the occasion of his 70th birthday Spectroscopic properties of YAG and YAP doped with F e were compared. YAG : F e crystals grown under reducing atmosphere showed strong colouration whereas similar colouration inYAP : F e wa
