Abstract: We report a second order lens effect detection in the 100 fs time region achieved in a LBO crystal with a Ti:sapphire laser. We implemented the already reported steady state theory which takes into account both the phase and amplitude modulation of the fundamental field affecting its subsequent propagation. We compare this lens effect with the classical Kerr effect with the purpose of realizing a passive modulation device evidencing the advantages of a stronger effect and the possibility of adjusting the magnitude and sign.
