Research In Laser Spectroscopy of Rare Earth Based Solids

When I arrived at Hamilton, I concentrated most of my effort on the spectroscopy of upconversion laser materials. I got into this field as a post-doc at IBM. I was a member of the Optical Storage group there that was working on the development of compact blue laser devices. An Upconversion Laser produces laser light at a higher frequency than the pump light - hence the name - and is one possible way of creating a blue laser using readily available infrared diode lasers as excitation sources. Our group at IBM built the first continuous upconversion laser and then developed several more lasers before I left in mid-87. Since then, the field has grown and many groups all over the world are working on upconversion.

More recently I have been working on synthesis and spectroscopy of Rare Earth doped sol-gel glasses. I collaborate on this project with Karen Brewer in the chemistry department here, Dan Boye from Davidson College, and Kurt Hoffman from Whitman College. Dan has put together a great web site where you can read about our recent students, papers, and grants.

We've had grants from Research Corporation and Petroleum Research Fund to support the project and have had many students make valuable contributions to the work. Dan and I presented posters on RE-based sol-gels at the Dynamic Processes Conferences in Christchurch (2003) and Segovia (2007) and at ICL '08- International Conference on Luminescence - in Lyon, France. Our group presented 3 posters and one talk at DPC '10, held at Argionne National Lab and we will have a poster at ICL '11 in Ann Arbor.

Recent Research Students and their Projects

Courses Taught

Over the years I have taught introductory physics for science majors and pre-meds, Quantum Physics, Classical Mechanics, and have directed senior research projects. Last fall I taught Physics190, our course for entering physics majors.This spring I have a junior-level advanced lab course designed to prepare students for their senior research projects.

Two years ago I taught a sophomore seminar with Ella Gant of the Art Department. It was called Art and Physics of the Image and was a lot of fun.
