Abstract
A broadband optical spectrum generating apparatus 20 includes a ultrashort pulsed fiber laser 22 that generates pulsed light having a pulse width in the unit of picosecond to femtosecond, and broadband optical spectrum-generating optical fibers 24 that are connected with the ultrashort pulse fiber laser 22 via a lens 26 and have characteristics of normal dispersion, that is, a nonlinear coefficient of not less than 10 [W−1 km−1] and a magnitude of wavelength dispersion of not greater than a value 0 [ps/km/nm] with regard to a wavelength of the pulsed light. The resulting output is super continuum that is widely broadened to a wavelength band of 1400 nm to 1750 nm and is chirped to a linear characteristic.
