We are currently investigating the physics that limit the performance of various materials that in turn limit the scaling of infrared laser sources to higher power. First, nonlinear optical crystals provide an efficient means for converting the power from well-established lasers to longer wavelengths. However, various point defects in many of these crystals such as CdSiP2 are responsible for the crystals’ infrared absorption that in turn leads to thermal lensing at higher laser power. Various ongoing projects range from the analysis of the crystal defects by an assortment of experimental techniques to modeling activities. Additional interest focuses on semiconductor lasers. Projects range from developing a better understanding of the properties of tensile strained germanium for infrared photon emission to investigating thermal energy transfer through heterogeneous semiconductor interfaces that fundamentally limits power scaling.
