Measurement of field-free molecular alignment by cross-defocusing assisted polarization spectroscopy.
We demonstrate the measurement of field-free molecular alignment of nitrogen by a cross-(de)focusing assisted polarization spectroscopy technique, allowing us to distinguish the transient orientation of prealigned molecules on the basis of the relative ratio of the adjacent revival peaks of the measured signal. For impulsive excitation with high pump intensities, the involved orientation-depend...
متن کاملField-Free Alignment and Strong Field Control of Molecular Rotors
Methods of controlling molecular rotations using linearly polarized femtosecond and picosecond pulses are considered and analyzed theoretically. These laser pulses, typically in the infrared, are highly non-resonant with respect to the electronic degrees of freedom of the molecules and have intensities of ∼ 10 to 10 W/cm. It is shown how these laser pulses can force small linear molecules to al...
متن کاملField-free molecular alignment control of filamentation
With an approach of controlling the nonlinearity of medium rather than the light field, the effect of field-free molecular alignment on filamentation and resulting white-light generation is studied. This is done by measuring the rotational wavepacket evolution of nitrogen molecules after passing of a femtosecond laser pump pulse by observing the nonlinear propagation dynamics of a variably dela...
متن کاملField-free three dimensional molecular axis alignment.
We investigate strategies for field-free three dimensional molecular axis alignment using strong nonresonant laser fields under experimentally realistic conditions. Using the polarizabilites and rotational constants of an asymmetric top rotor molecule (ethene, C2H4), we consider three different methods for axis alignment of a Boltzmann distribution of rotors at 4 K. Specifically, we compare the...
متن کاملOperational approach in the weak-field measurement of polarization fluctuations
The operational approach to the measurement of phase studied by Noh, Fougerès and Mandel is applied to the measurement of the state of polarization of fully polarized light. Operational counterparts of the quantum Stokes parameters are introduced and their fluctuations are examined. It is shown that, if the polarized field is weak, the measured fluctuations are influenced not only by the quantu...
