Two-dimensional ultrafast pulse shaping and its application to coherent control and spectroscopy
… excitations and degenerate four-wave mixing spectroscopy. Pulse shaping in two dimensions is achieved by manipulating the spectral components of ultrashort laser pulses within many horizontal slices of the pulse. Each horizontal slice is independently shaped by means of a two-dimensional …

Nonlinear optical microscopy and spectroscopy by pulse shaping of a coherent fiber supercontinuum
Nonlinear optical microscopy and spectroscopy enable three-dimensional sub-µm-resolution imaging with deeper penetration and reduced photodamage, and have been established as powerful methods in biomedicine. The most appealing aspect of nonlinear optical imaging is the wealth of molecular contrast …
