Second harmonic beam analysis, a sensitive technique to determine the duration of single ultrashort laser pulses.
In: optics communications, No. 30: pp. 453-457
The second harmonic beam generated in a noncollinear arrangement allows the observation of the autocorrelation functio: A compact optical beam splitter and imaging system eliminates alignment problems. Single pulses of 1 ps duration and approximately 10−8 joule energy are readily observed using an optical multichannel analyser.
