  1. Nonlinear Spectroscopy of Optical Ceramics Award DMR (CER-CIAM)# 0502715 - S.C. Rand, University of Michigan Nonlinear spectroscopy can probe the optical properties of advanced transparent ceramics designed for nonlinear optics and laser technology, with great precision. Nonlinear dynamics within multiply-doped ceramics can also produce novel emission from ceramics through upconversion processes (visible light from infrared excitation) that are enhanced by nano-structuring of the ceramics. Such multi-component materials present interesting prospects for upconversion lasers, displays, biomedical tracers, and metamaterials. By appropriate processing for example they can be formed into uniquely large or multi-functional optics for high power applications. Through nonlinear spectroscopy we are engaged in probing the modified bulk optical properties of these nano-structured solids, seeking to understand their unique structure-function relationship.

  2. Nonlinear Spectroscopy of Optical CeramicsAward DMR (CIAM)# 0502715 - S.C. Rand, University of Michigan One of the most effective ways of encouraging students to undertake careers in scientific research is through outreach to undergraduate researchers. For nanoscience to make an impact, future scientists need to experience success with tabletop experiments and become inspired. At the University of Michigan we have a regular program that provides research experiences for undergraduates (REUs). This project supported Mike De Palatis in experimental optical studies of coherent back-scattering from ceramic nanopowders during the summer of 2005, with additional support from the Dept. of Physics, Univ. of Michigan. In addition this year graduate student Bin Li, who demonstrated the first electrical generation and storage of stationary light in nanoceramic powders, was inspired to form the Ann Arbor student chapter of the Optical Society of America. This new chapter will provide opportunities to network with local industry personnel and foster careers in science and engineering research.
