Hi everybody,

Have some of you ever used a Rees spectrometer in place of an
autocorrelator.
As I understood, from the spectrum of the pulse, the analyser calculate the
duration.
I would like to optimize the duration of my femtosecond pulses. So I don't
need to know with precision the duration of each pulse.
This solution is much cheaper  than buying an autoccorelator.
In addition, I am not able to find a representative selling this kind of
sprectrometer analyzer.
Any comments or suggestions ?
Thanks you  very much
Stéphane
