…to be transform limited. As an example
a transform limited 800 nm, 100 fs pulse, will have a
bandwidth of 6.725 nm. In practice, a perfect pulse is
very hard to achieve, and for Ti:S lasers the bandwidth
is usually between 1.1-1.3 times higher than the
transform limit.

…Measurement
In order to measure properly the pulse of broadband
lasers like Vitara UBB (typically 7fs Transform limit for
<10 fs laser and 6 fs Transform Limit for <8 fs option)
we need to use the proper pulse measurement tool.
Many devices like FROGs, autocorrelators…

"transform limited" pulse independent of the actual shape of the pulse. If there is some chirp in the pulse, this procedure is not valid. I(t) = (F -1{I(n)1/2})2 (only valid when pulse is transform limited) Unfortunately, there is no direct procedure for determining if a pulse is transform limited.
