quantitative fluorescence and elastic scattering tissue polarimetry using an eigenvalue calibrated spectroscopic mueller matrix system
Optics Express, 2013Co-Authors: Jalpa Soni, Harsh Purwar, Harshit Lakhotia, Shubham Chandel, Chitram Banerjee, Uday Kumar, Nirmalya GhoshAbstract:A novel spectroscopic Mueller matrix system has been developed and explored for both fluorescence and elastic scattering polarimetric measurements from biological tissues. The 4 × 4 Mueller matrix measurement strategy is based on sixteen spectrally resolved (λ = 400 - 800 nm) measurements performed by sequentially generating and analyzing four Elliptical Polarization states. Eigenvalue calibration of the system ensured high accuracy of Mueller matrix measurement over a broad wavelength range, either for forward or backscattering geometry. The system was explored for quantitative fluorescence and elastic scattering spectroscopic polarimetric studies on normal and precancerous tissue sections from human uterine cervix. The fluorescence spectroscopic Mueller matrices yielded an interesting diattenuation parameter, exhibiting differences between normal and precancerous tissues.

nonadiabatic theory of strong field atomic effects under Elliptical Polarization
Journal of Chemical Physics, 2012Co-Authors: Xu Wang, J H EberlyAbstract:Elliptically polarized laser fields provide a new channel for access to strong-field processes that are either suppressed or not present under linear Polarization. Quantum theory is mostly unavailable for their analysis, and we report here results of a systematic study based on a classical ensemble theory with solution of the relevant ab inito time-dependent Newton equations for selected model atoms. The study's approach is necessarily nonadiabatic, as it follows individual electron trajectories leading to single, double, and triple ionizations. Of particular interest are new results bearing on open questions concerning experimental reports of unexplained species dependences as well as double-electron release times that are badly matched by a conventional adiabatic quantum tunneling theory. We also report the first analysis of electron trajectories for sequential and non-sequential triple ionization.

classical theory of high field atomic ionization using Elliptical Polarization
Physical Review A, 2012Co-Authors: Xu Wang, J H EberlyAbstract:Important information about strong-field atomic or molecular ionization can be missed when using linearly polarized laser fields. The field strength at which an electron was ionized and the time during a pulse of the ionization event are examples of such missing information. In treating single-, double-, and triple-ionization events we show that information of this kind is made readily available by the use of Elliptical Polarization.

Elliptical Polarization and probability of double ionization
Physical Review Letters, 2010Co-Authors: Xu Wang, J H EberlyAbstract:The degree of Elliptical Polarization of intense short laser pulses is shown to be related to the timing of strong-field nonsequential double ionization. Higher ellipticity is predicted to force the initiation of double ionization into a narrower time window, and this "pins" the ionizing field strength in an unexpected way, leading to the first experimentally testable formula for double ionization probability as a function of ellipticity.

effects of Elliptical Polarization on strong field short pulse double ionization
Physical Review Letters, 2009Co-Authors: Xu Wang, J H EberlyAbstract:We predict new end-of-pulse behavior in high-field atomic double ionization. Calculations of atomic electron trajectories in short intense laser pulses confirm our analysis of Elliptical Polarization. We exhibit a four-band structure in ion momentum distributions under various ellipticities, and predict that sequential and nonsequential double ionization can be cleanly distinguished under Elliptical Polarization.
