%X The goal of this work was the realisation of a setup for spectral broadening andsubsequent compression of 25 fs laser pulses provided by a commercial Ti:Sapphire basedCPA laser system by means of the hollow core ?bre chirped mirror compressor technique.For the spectral broadening a vessel containing the hollow waveguide ?lled with a noble gasserving as the nonlinear medium was set up and an alignment procedure was developed.Neon was chosen as the nonlinear medium for the self-phase modulation of the pulses.With this setup spectral broadening, su?cient for supporting sub 5 fs pulses, was observed.The spectra at di?erent input energies and neon gas pressures were measured and thestability of these and their respective Fourier transform-limited pulses determined in orderto ?nd an operating point. For the compression of the self-phase modulated pulses achirped mirror compressor was designed and set up, but not tested yet. The layoutofasingle-shot intensity autocorrelator capable of estimating the pulse duration of sub 10 fspulses was given.
