Radiation forces and confinement of neutral particles into the pulse envelope. New regime of collision ionization
L M Kovachev
The aim of this work is to find analytical expressions of the radiation force and potential densities arising from a laser pulse propagating in a dielectric media. In the femtoseco…
Dark states and vortex solutions with finite energy in Maxwell-Dirac nonlinear equations
Lubomir Kovachev
Starting from Maxwell equations for media with no-stationary linear and nonlinear polarization, we obtain a set of nonlinear Maxwell amplitude equations in approximation of first o…
Longitudinal Radiation Force of Laser Pulses and Optics of Moving Particles
Lubomir Kovachev
For a long time transverse and longitudinal optical forces are used for non-contact and noninvasive manipulation of small individual particles. The following question arises: What…
Solitons in non-paraxial optics
D. Dakova, A. Dakova, V. Slavchev +1
The well-known (1+1D) nonlinear Schrödinger equation (NSE) governs the propagation of narrow-band pulses in optical fibers and others one-dimensional structures. For exploration th…
The light filament as a new nonlinear polarization state
Lubomir M. Kovachev
We present an analytical approach to the theory of nonlinear propagation in gases of femtosecond optical pulses with broad-band spectrum . The vector character of the nonlinear thi…
The light filament as vector solitary wave
Lubomir M. Kovachev
We present an analytical approach to the theory of nonlinear propagation of femtosecond optical pulses with broad-band spectrum in gases. The vector character of the nonlinear thir…
