Paper Abstract

One TV-camera associated with a 64 K bytes digital memory. and a 8080 Microprocessor allows the treatment in real time of the spatial distribution of intensity in a single picosecond laser pulse used in multiphotonic experiments at 1 µ 06 wavelength. The silicon mosaic pickup tube employed for imaging is preilluminated for 200 isec before the arrival of the laser pulse in order to improve the linearity. The system is able to record 256 x 256 image elements and 256 amplitude levels. At present the number of significant levels is 64 but routine work is carried out using 32 levels, with color display of each amplitude level, and 5 seconds computations of the relative intensity value in a cross section of the beam.
