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.
