Abstract. The optical elements introduce additional spatial phase modulation which leads to a change of the evolution dynamics of the laser pulses. In the present work we consider the linear and nonlinear propagation of laser pulse phase modulated by double convex lens. Conditions for maximal compression and self-focusing of the pulse are found.
