The model and algorithms for analysis of the laser photoinduced processes were developed using numerical simulations. A statistics of the process was carried out by averaging over a hundred laser pulses. A special correction algorithm was created. A standard uncertainty of the results from the output laser signals without any correction was equal to 0.003527, while for the expected value was equal to about 1.000510. After correction procedure standard uncertainty of results was 0.000479 for the expected value equal to 0.999955. Due to the applied correction methodology of laser signal analysis, the uncertainty can decrease by one order of magnitude. The proposed approach may be used for describing photoinduced nonlinear optical processes with time duration from nanosecond to microsecond.
