sources the common things are restrictions to wavelength range and limited
spectral bandwidth. SC sources have contributed well in resolving these issues,
where band-width is responsible for astonishing resolution enormously. A longi-
tudinal resolution of only 2.5 μ m can be achieved in this way using a 1,210 nm
broad SC range lies between 390 and 1,600 nm, produced from a Ti:Sapphire
mode-locked laser by using 2 nJ 100 fs pulses [ 6 ].
The pumped systems having a range 1,060 nm are supposed to be very useful,
as a large flat stable continuum mostly by Raman scattering is created by the slow
pulses. The desired wavelength range can be selected by filtering large continuum-
filtering which is obtainable easily in, e.g., band gap guiding fibers, in which light
is made to be guided in only a limited wavelength range.
