By a wavepacket propagation, we demonstrate the possibility of controlling the photodissociation branching ratio between two fragment channels by a single ultrashort linearly chirped laser pulse. It is found that a negatively chirped pulse of a moderate chirp rate completely prohibits the production

β¦ Synopsis
Two models of femtosccond laser-stimulated desorption (LSD) are considered. One is the LSD due to a coherent "giant" optical mode vibration created by a femtosecond laser pulse and the other is the predesorption induced by a femtosecond UVvisible laser.

The simple analytical formula for description of the scattering of ultrashort laser pulse with the shape of the Meyer wavelet by atomic system is obtained. The dependence of the scattered pulse shape as a function of the system spectral width is discussed.
New mechanism of laser acceleration of a charged particle is discovered and explained. Particle acceleration with focused beam of superintense ultrashort laser pulse is determined by a combination of ponderomotive forces at rising and falling edges of laser pulse and a longitudinal component of lase
We report the matrix-assisted desorption of gramicidin D dissolved in a platinum matrix. The experimental data are interpreted by using the microcanonical model of laser desorption.
