Lez #21+22 Experimental techniques for pulsed laser characterization. Autocorrelator.

  We discussed different type of autocorrelation techniques for measuring the duration of ultrashort pulses, namely linear autocorrelator, non-collinear SHG autocorrelator and collinear SHG autocorrelator, discussing the different advantages/disadvantages. We also introduced FROG (frequency-resolved optical gating) as a convenient approach to characterize an optical pulse.
