- The work concerns application of titanium-sapphire femtosecond laser oscillator with 82 MHz repetition rate at 800 nm in measurements of ultrafast magneto-optical and magnetization-induced second harmonic generation effects. Time-resolved magneto-optical Kerr effect pump-probe method was used in investigation of ultrafast precession of magnetization in Fe/Au multilayers. Magnetization precession frequency, obtained as a function of magnetic field applied, allows determining saturation magnetization and damping factor. The magnetization-induced second harmonic generation effect has been used for study of garnet films. This method allows to determine crystallographic symmetry and hysteresis loops in an external magnetic field at 2 ω laser induced frequency. The simultaneous measurements of linear and second order magneto-optical effects enable to investigate magnetic interfaces in the studied structures.
