Abstract
A light source is provided. The light source includes: a discharge lamp in which a pair of electrodes facing each other is disposed and a discharge medium is enclosed; and an energy beam irradiation unit that emits an energy beam toward a gap between the pair of electrodes. The energy beam irradiation unit emits the energy beam toward a bright spot that is formed near a tip end of the electrode when the discharge lamp is turned on by applying a voltage to the electrodes.
