White Light Continuum for Broadband Nonlinear Spectroscopy
Supercontinuum (SC) generation, oftentimes referred to as white-light continuum (WLC), has been a subject of interest for more than 40 years. From the first observation of WLC in condensed media in the early 1970s to the first observation of WLC in gases in the mid-1980s, much work has been devoted …

Experimental Techniques For Nonlinear Material Characterization: A Nonlinear Spectrometer Using A White-light Continuum Z-scan
… regions. However, conventional methods like, white-light continuum pump-probe and Z-scan techniques were used to measure the peak 2PA cross-sections for a number of commercially available photoinitiators. In the new method mentioned above, a high energy, broadband femtosecond white-light …

Few-cycle and cavity-enhanced optical parametric amplification
… amplification based sources. First, we present a white light seeded, carrier-envelope stable, degenerately pumped OPA producing near tranform-limited sub 7 fs , 3 [mu]J pulses at the driver wavelength from a long pulse, non-CEP stable Ti:sapphire regenerative amplifier. Problems to the spectral …

Coherent Control of Molecular Dynamics with Shaped Femtosecond Pulses
… to date. Using a pulse shaper to modulate the white light continuum that serves as the seed for the non-collinear optical parametric amplifier, generation of phase-locked two-color double pulses has been achieved, with tunable wavelengths, delays, and relative carrier phases between the single …
