Rapid proton transfer mediated by a strong laser field.

چکیده
Kinetic energy distributions of ejected from a polyatomic molecule, anthraquinone, subjected to 60 fs, 800 nm laser pulses of intensity between 0.2 and 4.0 x 10(14) W x cm(-2), reveal field-driven restructuring of the molecule prior to Coulomb explosion. Calculations demonstrate fast intramolecular proton migration into a field-dressed metastable potential energy minimum. The proton migration occurs in the direction perpendicular to the polarization of the laser field. Rapid field-mediated isomerization is an important new phenomenon in coupling of polyatomic molecules with intense lasers.

We have studied excitation of multilevel Na-Rydberg atom due to collision with proton in the presence of variable laser field. The interaction of laser field and Na-Rydberg atom is explored using non perturbative Floquet technique. The transition probability is calculated at different laser frequencies (GHz), projectile velocities and impact-parameter. We have also calculated total cross-sectio...
متن کاملAnalysis of the theory of thermal damage in biological tissues caused by Laser beam
Introduction: In laser surgery, the laser beam can evaporate and cut the tissue like a small surgical knife when the tissue temperature is heated to 100 degrees Celsius. a complete understanding of the distribution of damage in both pathologic tissue and surrounding tissue is necessary. Although the test is the most realistic solution for treating medical problems, for this rea...
متن کاملProspects of target nanostructuring for laser proton acceleration
In laser-based proton acceleration, nanostructured targets hold the promise to allow for significantly boosted proton energies due to strong increase of laser absorption. We used laser-induced periodic surface structures generated in-situ as a very fast and economic way to produce nanostructured targets capable of high-repetition rate applications. Both in experiment and theory, we investigate ...
