ABSTRACT:
A broadband optical spectrum generating apparatus20includes a ultrashort pulsed fiber laser22that generates pulsed light having a pulse width in the unit of picosecond to femtosecond, and broadband optical spectrum-generating optical fibers24that are connected with the ultrashort pulse fiber laser22via a lens26and have characteristics of normal dispersion, that is, a nonlinear coefficient of not less than 10 [W−1km−1] and a magnitude of wavelength dispersion of not greater than a value 0 [ps/km
m] 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.
