Spectral shaping of SC in a photonic crystal fibre: polarization, pulse duration and chirp properties

Summary from only given. We present results of experiment aiming to generate smooth spectrum in the range 500-1100 nm with the use of chirp and polarization adjustments of the incident pulse as well as its duration. No numerical simulations are known on this subject mainly because of the difficulties in 3D modelling the complex PCF-structure; as well as no systematical experimental results are known. The polarization dependence can be explained with the multifrigency of the PCF, due to its broken azimuthal symmetry.
