A system for controlling plasma position in extreme ultraviolet lithography light sources may include a vacuum chamber, a droplet generator to dispense a stream of droplets into the vacuum chamber, wherein the droplets are formed from a metal material, a laser light source to fire a plurality of laser pulses, including at least a first pulse and a second pulse, into the vacuum chamber, a sensor to detect an observed plasma position within the chamber, wherein the observed plasma position comprises a position at which the plurality of laser pulses vaporizes a droplet of the stream of droplets to produce a plasma that emits extreme ultraviolet radiation, and a first feedback loop connecting the sensor to the laser light source, wherein the first feedback loop adjusts a time delay between the first and second pulses to minimize a difference between the observed plasma position and a target plasma position.
