A photoflash capacitor is a high-voltage electrolytic capacitor used in camera flashes and in solid-state laser power supplies. Their usual purpose is to briefly power a flash lamp, used to illuminate

Flashtube

A flashtube produces an electrostatic discharge with an extremely intense, incoherent, full-spectrum white light for a very short time. A flashtube is a glass tube with an electrode at each end and is
Flashtubes of various sizes for laser pumping. The top three are xenon flashtubes. The last one is a krypton arc lamp, (shown for comparison).
Xenon flashtubes used on smartphones and cameras are usually externally triggered.
