Biography:
Dr. Althea G. Bluiett is an assistant professor in physics in the department of Chemistry, Geology, and Physics. Currently, ongoing research is being conducted in exploring new mid-infrared materials for military applications as well as basic research.

Research interest:

My research interest concerns the crystal growth and optical characterization of rare earth (RE) doped solid-state materials. Currently, with the assistance of Army grant-W911NF-06-1-047, I have ongoing research on exploring the potential of sensitizing rare-earth ions for mid-infrared emission in the 4-5 ┬Ám regime. In this work, the excited state dynamics of trivalent RE-ions will be modified by employing a sensitization pumping scheme. This pump scheme will simultaneously take advantage of two RE-ions. One RE-ion will resonantly absorb the pump radiation, which is defined as the sensitizer or donor ion. A fraction of the absorbed pump radiation is subsequently transferred to the second RE-ion, the activator or acceptor ion. The activator ion emits the MIR light that is responsible for the laser emission. The sensitization scheme basically takes advantage of the strong absorption cross-section and convenient absorption wavelength of the sensitizer ion, and the intra-4f mid-infrared transition of the activator ion. The host materials under investigation includes KPb2Cl5 and KPb2Br5. The dopant materials include various combinations of the following RE-ions: Tm, Nd, Er, Dy, Pr, Tb, and Yb.
