Applied Physics Letters, 2009 We have observed optical birefringence in liquids induced by single-cycle terahertz pulses with field strengths exceeding 100 kV/cm. The induced change in polarization is proportional to the square of the terahertz electric field. The time-dependent terahertz Kerr signal is composed of a fast electronic response that follows the individual cycles of ...

The phase shift induced by a single atom in free space [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In this article we theoretically study the phase shift a single atom imprints onto a coherent state light beam in free space. The calculations are performed in a semiclassical framework.

Intense femtosecond optical pulse shaping approaches to spatiotemporal control
Frontiers in Chemistry, 2023 For studying any event, measurement can never be enough; “control” is required. This means mere passive tracking of the event is insufficient and being able to manipulate it is necessary.
