Nonuniform Atmospheric Scatter of Short-Pulse Optical Radiation
The results of calculation of the mean intensity of spatially partially coherent pulsed optical beam scattered by an atmospheric layer are presented. It is shown that in contrast to cw radiation, which scatters uniformly, the scatter of pulsed beam becomes nonuniform for shorter pulses. For the femt...

Summary: | The results of calculation of the mean intensity of spatially partially coherent pulsed optical beam scattered by an atmospheric layer are presented. It is shown that in contrast to cw radiation, which scatters uniformly, the scatter of pulsed beam becomes nonuniform for shorter pulses. For the femtosecond pulse duration the backscattered radiation is localized near the strictly backward direction in the area with transverse dimensions comparable with the initial size of the sensing beam. |
