A passive peak intensity stabilization method based on optimal combination of Kerr nonlinearity and linear dispersion is presented. By analyzing the Kerr nonlinearity with a 3D numerical model it was found that if a Gaussian laser pulse acquires a certain amount of nonlinear phase and is consequently over-compressed to have sight negative chirp, the uctuations in peak intensity caused by energy uctuations are reduced. Thus, even if the energy of laser pulses uctuates the peak intensity can be stabilized. The simulations for realistic pulse parameters show an increase in peak intensity stability by well-over an order of magnitude. We demonstrate this process experimentally using a thin disk pump laser at ELI Beamlines
