Coherent Radiation Sources

Energetic electromagnetic radiation finds frequent uses in science (e. g. , for expe­ riments in nuclear and elementary - particle physics), in technology (for materials testing), and in medicine (for medical X-rays). The most common method of genera­ ting such radiation is via the process of "bremsstrahlung" (a German term coined by A. Sommerfeld, meaning "braking radiation") in which a beam of e...
