Abstract
Nd:YAG lasers have become ubiquitous as tools for spectroscopy, materials processing, and
medical care. It is well known by crystal growers that lattice defects in Nd:YAG can stifle
laser efficiency, but to date very little has been done to isolate and characterize individual
YAG defects. Knowing the spectral characteristics of these defects would make detection of
distinct defects in a sample possible. This thesis describes a set of experiments performed
to characterize these defects spectroscopically.
