Generation of smooth, ultra-broadband spectra directly from a prism-less Ti:sapphire laser

Ultra-broad and smooth spectra are generated directly from a mirror-dispersion-controlled Kerr-lens mode-locked Ti:sapphire oscillator. The full width at half maximum of the spectrum is 277 nm. The pulse width is evaluated as 6.5 fs by using both interferometric autocorrelation and spectral phase in...

Description
Summary:Ultra-broad and smooth spectra are generated directly from a mirror-dispersion-controlled Kerr-lens mode-locked Ti:sapphire oscillator. The full width at half maximum of the spectrum is 277 nm. The pulse width is evaluated as 6.5 fs by using both interferometric autocorrelation and spectral phase interferometry for electric-field reconstruction. This compact, user-friendly source opens the door to routine implementation of ultra-high-resolution as well as spectroscopic optical coherence tomography in a clinical environment.
