Abstract

The present invention generally relates to a process for fabricating Chloro Alkali Phosphate Doped/Codoped by rare earth ions for optical laser amplifiers. The process includes mixing 38-42 wt. % of Phosphorus pentoxide (P₂O₅), 28-32 wt. % of Zinc oxide (ZnO), 9-11 wt. % of Barium fluoride (BaF₂), 17-19 wt. % of Lithium chloride (LiCl), and 1-3 wt. % of Lead(II) fluoride (PbF₂); filling a silica, platinum, and alumina crucible to the mixture; heating the mixture upon increasing a furnace temperature to 1000-1050° C. at a rate of 10° C. per minute and maintaining it for two hours to melt the glass; and pouring the glass melt into a preheated stainless steel mold at 350° C. and transferring the mold to a holding furnace heated to 350-370° C. and annealing for two hours thereby cooling to room temperature to obtain Chloro Alkali Phosphate matrix glass that is undoped, doped, or codoped with high thermal stability.
