Abstract:Frequency Resolved Optical Gating (FROG) is the most commonly used apparatus for
diagnostics of ultra-short laser pulses. FROG consists of two components: an optical
module and a reconstruction algorithm. For a given optical module, existing algorithms
limit several properties of the FROG device, including the range of pulses that can be
characterized. I will present a new reconstruction approach that utilizes typically existing
prior information about measured pulses for significantly improving the properties of the
FROG device. Numerical and experimental results will be presented.
