To prepare Nd-doped SiO 2 glasses by axial injection plasma torch CVD, a special type of NdCl 3 gas generator for axial injection was developed and its optimum operating conditions were examined. The technical advantages and disadvantages of this method were discussed in comparison with previously reported tail injection plasma torch CVD. Although a large difference exists between these two methods, little difference in the fluorescence properties of the resultant glasses was observed.
