For measuring the pulse duration of single ultra short laser pulses in SSA is used method based on the registration of cross distribution of Second Harmonic (SH) energy
produced in nonlinear crystal under noncollinear interaction of two beams with determined aperture. The main idea of the method is illustrated in Fig.1 (see manual) for the simplified case when
initial laser pulse has rectangular time shape and uniform intensity cross distribution. Two identical pulses are produced by Beam Splitter (BS) from initial laser pulse. The SH is
generated in the field of pulse superposition in nonlinear crystal.
