Abstract
The full intensity-and-phase characterization of ultrashort laser pulses is now routine in scientific research. Techniques such as frequency-resolved optical gating (FROG) [1] have been widely applied to obtain such information, which is essential in many applications. However, what we have been able to measure so far are mostly simple laser pulses. There are many more light pulses in general, and they aren’t always emitted by lasers, and they can be extremely complicated, very weak, and quite variable from shot to shot. Many more applications involve these “ill-conditioned” pulses, and the ability to measure these pulses will be an invaluable tool to many researchers. In this report we extend the FROG technique to the measurement of ultracomplex (supercontinuum) and ultraweak (bioluminescence) light pulses. Only minor modifications to the FROG apparatus and algorithm are required for these measurements.
