Mathematical Treatment of Infrared Multiphoton Dissociation Induced by Non-Uniform Non-Gaussian Laser Beam.

Influence of non-gaussian laser beam profiles on proton acceleration

10 12 V/m. The acceleration was found to take place within a few ps only. The beam always is directed normal to the rear surface of the target with an emittance being superior compared to conventional accelerator beams [2, 3]. The laser pulse accelerates electrons to relativistic energies in the front side preplasma formed by the prepulse. They penetrate the target and escape at the rear side. ...

Infrared multiphoton dissociation of two perfluorobutenes

Electron Detachment Dissociation and Infrared Multiphoton Dissociation of Heparin Tetrasaccharides.

Heparin glycosaminoglycans (GAGs) present the most difficult glycoform for analytical characterization due to high levels of sulfation and structural heterogeneity. Recent contamination of the clinical heparin supply and subsequent fatalities has highlighted the need for sensitive methodologies of analysis. In the last decade, tandem mass spectrometry has been increasingly applied for the analy...

Measuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry

Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...

Far-field scattering of a non-Gaussian off-axis axisymmetric laser beam by a spherical particle.

Experimental laser beam profiles often deviate somewhat from the ideal Gaussian shape of the axisymmetric TEM(00) laser mode. To take these deviations into account when calculating light scattering of an off-axis beam by a spherical particle, we use our phase-modeling method to approximate the beam-shape coefficients in the partial wave expansion of an experimental laser beam. We then use these...
