Abstract
Provided is a two-photon spectroscopy including a light source configured to generate first laser light having a pulse, a pulse width correction device configured to receive the first laser light to output a second laser light, an optical system through which the second laser light passes, a first two-photon sensor configured to measure a first pulse width of the first laser light generated from the light source, and a second two-photon sensor configured to measure a second pulse width of the second laser light passing through the optical system, wherein the pulse width correction device corrects a difference between the first pulse width and the second pulse width.
