A '''photoflash capacitor''' is a high-voltage [[electrolytic capacitor]] used in [[camera]] [[flash (photography)|flash]]es and in solid-state [[laser]] power supplies. Their usual purpose is to briefly power a [[flash tube|flash lamp]], used to illuminate a photographic subject or optically pump a laser rod. As flash tubes require very high current for a very short time to operate, photoflash capacitors are designed to supply high discharge current pulses without excessive internal heating.
