To give you an idea of how FROG and GRENOUILLE work and why they're useful, we've written a few tutorials that you can read or download. For more information, please refer to Prof. Rick Trebino's book, Frequency-Resolved Optical Gating: The Measurement of Ultrashort Laser Pulses, available from Kluwer Academic Publishers. Much of these tutorials has been excerpted from this book, so if you like them, you'll love the book! Indeed, it makes great bedtime reading.
