Two-photon excitation work featured in spectroscopy journal

  The cover photograph and feature paper in the February 1997 issue of Applied Spectroscopy (volume51, number 2, pages 218-226) are based on work done by Walt Fisher and Eric Wachter of the Advanced Photonics Applications Laboratory in the Life Sciences Division Assessment Technology Section. The paper presented results of research on two-photon excitation-the basic process used for their proposed non-invasive breast cancer therapy technique. It deals with the fundamental parameters of the self mode-locked titanium:sapphire laser relative to the application of this source for two-photon excitation fluorimetry studies. Walt Fisher is the principal author of the paper, and members of the Coherent Laser Group, who provided some equipment for this work, are co-authors. This photonics-based breast cancer therapy has received significant media interest over the past several months.
