摘要:

A rapid scanning autocorrelation interferometer for measurements of ultrafast laser pulses is described. The optical system is based on a new type of beam splitter allowing one to send all of the input beam power to the SHG crystal making the SHG signal four times greater than in the standard designs. Autocorrelation measurements of transform limited picosecond pulses from a synchronously pumped mode‐locked dye laser are presented.

摘要:

It is shown that in the paper written by M. Froeyen and L. Hellemans [Rev. Sci. Instrum.56, 2325 (1985)], the algorithm POL2*FFT proposed by myself and S. K. Ghosh [S. Sorella and S. K. Ghosh, Rev. Sci. Instrum.55, 1348 (1984)] is used in a incorrect way, because the original paper was not very ‘‘explicit’’ in some steps. Therefore, the new algorithm represents only a different application of our general strategy.

摘要:

The difference between Sorella and Ghosh’s approach [Rev. Sci. Instrum.55, 1348 (1984)] and ours [M. Froeyen and L. Hellemans, Rev. Sci. Instrum.56, 2325 (1985)] to obtain an expression for the Fourier transform of discrete data is highlighted. A practical advantage of our algorithm over Sorella’s is stressed.
