The optical output system includes a first laser that outputs a first light that is a pulse laser according to an input signal, a second laser that outputs a second light that is a pulse laser according to an input signal, and the first laser and the second laser. A calculator for inputting a signal is provided, wherein the calculator repeatedly inputs a signal by switching a plurality of variable delay values that are a difference between a timing of inputting a signal to the first laser and a timing of inputting a signal to the second laser.
