QUESTION: Can we prepare multi element rare earth anhydrous boats?
ANSWER:
Yes. This can be done by mixing the precursor rare earth compounds when preparing a halide batch. The most relevant application that comes to mind is the fabrication of Er/Yb doped preforms. It may be necessary to adjust the batch concentration ratio to achieve the desired atomic ratio of the elements in the core glass.
