Paper Abstract

Several simple single-beam non-interferometric measuring techniques for ultrashort laser pulse analysis have been proposed lately (e.g. MIIPS, dispersoscopy). They are based on a compensation of the pulse spectral phase by an acousto-optic pulse shaper followed by a SHG crystal, for example . The output signal is detected by a nonlinear optical medium. Dispersoscopy was originally verified by broadband pulses of Ti:sapphire oscillator and has never been tested in different spectral range or on narrow band subpicosecond pulses. We modified such a dispersoscope for measurement of sub picosecond pulses of an Yb:YAG renerative amplifier generating at wavelength of 1030nm. We also modified the device for measurement of picosecond pulses having their mid-IR wavelength in the range between 2 and 3 microns.
