Abstract
To provide a light source apparatus for light measurement in which time wavelength uniqueness is not lost even in a case of high output, and to enable spectroscopic measurement with high accuracy and at high speed. Broadband pulsed light having a continuous spectrum over a wavelength width of at least 50 nm in a range of 900 to 1300 nm is emitted from a pulsed light source, and divided for each wavelength by a divider, and light having each wavelength is transmitted by each of stretch fibers and emitted from a coupler. The stretch fibers have different lengths such that an elapsed time and the wavelength in one pulse correspond to each other on a one-to-one basis at an emission end.
