DURIP97 Femtosecond Vibrational Spectroscopy of Shock Waves in Materials

摘要

This grant provided partial funding for the acquisition of a powerful femtosecondlaser. The laser is to be used in making femtosecond time resolved measurements of shock waves in molecular materials, with the eventual application being understanding the sensitivity to shock initiation of energetic materials. After suitable negotiations, a CPA 10 laser from Clark-MXR Corporation was selected and ordered. To save money, some parts and diagnostic equipment were ordered and shipped to Clark for inclusion in the finished system. The laser was delivered in Oct. 1997. In the last several months, warranty repairs and improvements were made on the laser and the experimental set up is being constructed.
