    • The object is to measure the carrier envelope offset frequency of a mode-locked laser. Provided is a pulse laser that measures a carrier envelope offset frequency of a mode-locked laser, pulse laser comprising a mode-locked laser that generates an optical pulse; a band expanding section that expands an oscillated frequency range of the mode-locked laser; a harmonic generating section that generates a harmonic component of the mode-locked laser; a light transmitting section that inputs light to the harmonic generating section without changing relative timings of a predetermined frequency component of the mode-locked laser output from the band expanding section and a frequency component that is at least double the predetermined frequency component; a detecting section that detects a beat signal of the harmonic component and the component passed through the harmonic generating section by the mode-locked laser; and a calculating section that calculates a carrier envelope offset frequency and a repeating frequency based on the beat signal.
