A MRL alumnus, Dr. Andrew J. Birnbaum, received a 3rd place award for his presentation, "Pre-heated Substrate Effects on Meltmediated Laser Crystallization on NiTi Thin Films " at the 2008 International Congress on Applications of Lasers & Electro-Optics (ICALEO). The paper is co-authored with his thesis advisor, Prof. Larry Yao, as well as Prof. James Im of Materials Sciences, and Prof. Ainissa Ramirez of Yale University. Andrew's work investigates the effects of solidification rate on NiTi thin films subjected to a pulsed, melt-mediated laser crystallization technique. A high degree of control over the microstructure as well as the constitutive response of laser irradiated films is demonstrated. The ICALEO is devoted to the field of laser materials processing and is viewed as the premier source of technical information in the field. (link)
