Abstract :
Summary form only given. SHG FROG has an ambiguity in the direction of time and restrictions on the thickness of the nonlinear crystal due to phase matching for the large bandwidths needed to support such short pulses. In large amplified systems, a polarisation gate (PG) FROG would be much more desirable. The shot-to-shot stability of these systems makes single shot measurements necessary, which puts a premium on having a nonlinear medium with high optical quality.
