We discuss class policies and a bit of background and history on spectroscopy and lasers. Laser spectroscopy is an established field of chemistry and physics that uses the advantages of laser sources for spectroscopic measurements of atomic and molecular systems. This class covers laser sources, instrumentation, techniques and theory associated with the interaction of light and matter. It will provide both theoretical insight and provide an overview of experimental techniques that are relevant to this field. http://www.sjsu.edu/faculty/beyersdorf/Phys268/1-23%20Introduction%20to%20Laser%20Spectroscopy.m4a Wed, 23 Jan 2008 21:14:31 -0800 Natural Sciences no 01:08:57 chem 268, byersdorf, beiersdorf Peter Beyersdorf Class Syllabus (green sheet) Class Syllabus (green sheet) http://www.sjsu.edu/faculty/beyersdorf/Phys268/Physics%20268%20Syllabus.pdf Thu, 10 Jan 2008 10:52:10 -0800 Natural Sciences no 00:00:00
