Extremely simple intensity-and-phase ultrashort-pulse measurement device with no spectrometer, thin crystal, or delay line

Summary form only given.Ultrashort-pulse measurement remains a difficult task. Frequency-resolved optical gating (FROG), a spectrally resolved autocorrelation, is the simplest reliable intensity-and-phase measurement device. But the addition of a spectrometer to an autocorrelator complicates the apparatus. We have developed a remarkably simple pulse-measurement device that 1) uses no spectrometer, 2) uses no beam-splitter or delay line, 3) uses a more convenient, thick SHG crystal, and 4) yields about a thousand times more signal. It involves no sensitive alignment parameters. We call this new device grating eliminated no-nonsense observation of ultrafast incident light E-fields (GRENOUILLE).
