  2. Introduction Two broadband supercontinuum sources Jibe- white light continuum generator (T:Sapphire laser) Cannon- based on ultrafast fiber laser source

  3. Introduction • The generation of broadband supercontinuum spectra by injection of high-power ultrashort pulses into nonlinear optical media has been a subject of intensive research • When a high-intensity ultrashort pulse is focused into a transparent medium, a white-light continuum ranging from ultraviolet to infrared is generated

  4. Applications • optical parametric amplification • an optical metrology • an optical coherence tomography • materials characterization • pump-probe measurements

  5. Kerr effect n(I)=n0 + n2I+… n0- normal reflective index of the medium n2- the nonlinear reflective index Optical phase:ωL n/c

  6. Kerr effect E(t) cos (ωt-kx) - electic field of a laser pulse k= ωn/c –wavenumber Taylor expansion around the peak of the ultrafast pulse: E(t) cos((ω+ ξt)t - kx) ξ - depends on the nonlinear refractive index, the pulse width, peak of power and distance travelled

  7. Generation of White light Red wavelengths of the white light pulse travel faster than blue wavelengths

  8. Chirp on an ultrashort pulse

  9. Jibe S Jibe C Spectral coverage Nonlinear material Sapphire CaF2 Jibe - WLCG 450-900 nm 350-750 nm

  10. Spectrum of white light continuum Intensity Wavelength, nm

  11. Femtosecond laser R Probe Beam B.S. R R D R R R Pump Beam Harmonic Generator / OPA Chopper F.O. Delay line R R S R Pump-probe measurements WLCG can be easily integrated to the pump-probe system WLCG

  12. Pump-probe measurements The result is a plot of time delay vs. absorption/ transmission The typical three-dimensional data example of Ni(II) tetraphenyltetrabenzoporphyrin (NiTPTBP) in benzene

  13. Cannon –ultra-broadband light source Ultra-Broadband Light Source. Based on our ultra fast fiber laser source. This system provides a turnkey, portable source of broadband laser pulses without requiring any user-adjustments to the fiber coupling.

  14. Typical output spectrum

  15. Applications • telecommunication • optical Coherence Tomography • optical Component Testing • flourescence Spectroscopy of Biological Markers

  16. Specification • Optical Spectrum covers 1000 - 1900 nm • Average Output Power > 80 mW • Repetition Rate 50 - 70 MHz • Head size: 180x210x70
