<div><font size="3">Synchrotron radiation is a key consideration in the design of electron or positron accelerators. As a tool for probing and imaging matter on the scales from Angstroms to centimeters, it has become an indispensable
tool for many thousands of physicists, chemists, biologists and geologists. It has proven to be a powerful specialized tool for archaeologists and art historians as well. Free-electron lasers are specialized sources of synchrotron radiation that create and
exploit the collective motion of electrons in accelerators to produce extremely short burst s of light so intense as to be usable for freeze-frame photography of atoms and molecules under static conditions and amidst dynamic processes such as the breaking
of chemical bonds.</font></div>
<div><font size="3"> </font></div>
<div align="left"><font size="3">I will attempt to give a brief description of the properties of synchrotron radiation and some examples of experimental techniques they enable. I will describe basic
characteristics of accelerators optimized as light sources and free-electron lasers. I will also give an overview of light sources and free-electron lasers operating now and in planning or construction worldwide</font></div>
