This paper compares models based on nonlinear Maxwell’s and Schrödinger equations developed for modeling typical experiments involving the three-dimensional modification of glasses (using fused quartz as an example) under the action of femtosecond laser pulses. It is shown that the results can be appreciably different when the Maxwell’s and Schrödinger equations are used. A substantial role in this case is played not only by the equations themselves, but also by the form of the boundary condition that describes the focused laser pulse at the input to the region of calculation.
