The amplitudes and phases of femtosecond pulses generated from a home-made KLM Ti: Sapphire laser are diagnosed by using the technique of second-harmonic generation frequency-resolved optical gating. The results indicate that the profiles of the pulses are sech2 shapes and the phases are approximately cub ic dependent of the time. The chirped pulses of 17 fs(FWHM) are compressed to near Fourier transform limited pulses of 8.5 fs with a double-prism system to compensate for the second-order dispersion.
