You're creating 21st-century ultrashort laser pulses...
why measure them with mid-20th century methods?

Autocorrelators, invented in the 1960s, haven't changed much since then. At best, they still yield a poor measure of an ultrashort laser pulse's width, and, worse, they say nothing at all about the pulse's phase. And don't even ask about spatio-temporal pulse distortions!

Autocorrelators are complex, require much setup time, and need frequent maintenance. And the accuracy of such autocorrelations is further complicated by spatio-temporal distortions—like spatial chirp and pulse-front tilt—which plague ultrashort pulses and can seriously distort autocorrelations, not to mention important experimental data.

Recently invented GRENOUILLE, on the other hand, easily measures nearly everything you could possibly need to know about a pulse, and it does so without making any assumptions. Now that's true 21st-century pulse measurement! Plus, Swamp Optics' GRENOUILLEs are simple and compact devices for comprehensive characterization of ultrashort laser pulses.

For details on our GRENOUILLE offerings, refer to the following pages:

• GRENOUILLE Overview:  GRENOUILLE basics and capabilities.
• GRENOUILLE Tutorial:  Operational details and the science behind GRENOUILLE.
• GRENOUILLE Configuration:  Typical GRENOUILLE setup options.
• GRENOUILLE Specifications:  GRENOUILLE features and detailed specifications.

GRENOUILLE can operate alone—yielding the FROG spectrogram on a video monitor—or with a frame-grabber and FROG algorithm software—yielding the full intensity and phase of your pulse, as well as the beam spatial profile, spatial chirp, and pulse-front tilt. Available software and hardware sources include:
