摘要：

The abilities of new algorithm - 2D Fast Fourier Interpolation (FFI) with magnification factor (zoom) 2(n) to improve the spatial resolution when necessary are analyzed in details. FFI procedure is useful when diaphragm/aperture size is less than half of current simulation scale. The computation noise due to FFI procedure is less than 10(-6). The additional time for FFI is approximately equal to one Fast Fourier Transform execution time. For some applications using of FFI procedure decreases the execution time in 10(4) times compared with other laser simulation codes.
