Abstract
A wavelength error for each pulse in a first subset of pulses emitted from an optical source is determined, the wavelength error being the difference between a wavelength for a particular pulse and a target wavelength; a pulse-by-pulse correction signal is determined based on the determined wavelength error, the pulse-by-pulse correction signal including a correction signal associated with each pulse in the first subset of pulses; and a correction based on the determined pulse-by-pulse correction signal is applied to each pulse in a second subset of pulses emitted from the optical source, where applying a correction to a pulse in the second subset of pulses reduces the wavelength error of the pulse in the second subset of pulses.
