"Ultrafast Optical Pulses: Synthesis and Applications"

Kai Wang

Ultrashort laser pulses open exciting opportunities and promise discoveries in ultrafast atomic and molecular physics. We develop a technique for production of pulses whose duration is shorter than one optical field cycle, providing a potential for non-sinusoidal field synthesis. Our technique, termed Molecular Modulation, relies on broadband coherent Raman scattering which provides the required optical bandwidth. We demonstrate spectral phase control and waveform synthesis, with the assistance of either a deformable mirror, or a pulse shaper based on an acousto-optic programmable dispersive filter. Moreover, we work on applications that involve ultrashort optical pulses, and, as one example, perform sub-diffraction imaging of remote objects by using a single femtosecond laser filament.
