The experimental laser physics laboratory houses experiments studying laser-matter interactions. Many of these experiments involve photothermal techniques in which information about the absorption of a material is obtained by detecting the change in the sample due to absorption-caused local heating. These techniques can be used to locate and study in detail the defects that give rise to absorption in high quality optical materials. Over the years funding sources have included the State of Michigan, the National Science Foundation, and industry.
The lab uses an extensive range of equipment including:
