The indirect measurement method of the temporal profile and spectrum of Femtosecond Laser Pulses (FLP) carried out by the multi-beam cross-correlator is described. The method of temporal scaling of the single-shot irreproducible FLP under investigation was applied by scanning of the broadened FLP spectrum by pulses of a given shape at various wavelengths in a non-linear crystal. As a result of such an interaction a dynamic spectrogram is formed at the output of the non-linear crystal, from which the temporal profile and spectrum of the investigating FLP is defined.
The report gives the result of image K008 camera/1, 2/ application in trial experiments on laser sounding of water width from the air to determine the possibility of detecting and identifying objects dipped into the water and in the future for detecting and identifying objects dipped into the water and in the future for detecting a parasitic water-plant in the Sevang Lake in Armenia and drawing a map of its distribution across the depth throughout aquatory of the Lake.
