Custom Pulse-measurement Devices

If your pulse-measurement problem is unusual, and Swamp Optics doesn’t offer a standard FROG or GRENOUILLE to do it, that doesn’t mean it can’t be done!

Frequency-Resolved Optical Gating (FROG) is the first technique ever to accurately measure the intensity and phase of ultrashort light pulses. Invented by Swamp Optics' Rick Trebino (and D. J. Kane) in 1991, FROG has been used to measure ultrashort pulses in the IR, visible, UV, and, recently, x-ray regions of the spectrum. It has measured pulses as short as attoseconds and as long as many picoseconds. FROG can measure a single pulse or average over many, and it can also measure complex pulses (other techniques that purport to measure intensity and phase cannot and hence will not, so be careful!).

Swamp Optics will be happy to design a custom pulse-measurement device for almost any application. Whether your pulse is several ps long and in the UV or IR, we can build a device for you. (For reference, see the related paper, Experimentally simple, extremely broadband transient-grating frequency-resolved-optical gating arrangement. In Adobe Acrobat PDF format.)

Or if you need to measure ultrabroadband continuum, we can provide the device you need at less cost then you'd expect (see the related paper, Frequency-resolved optical gating and single-shot spectral measurements reveal fine structure in microstructure-fiber continuum. In PDF format).

Even if you require the pulse's complete spatio-temporal intensity and phase-E(x,y,z,t)—and on a single shot, we can help (see Single-shot measurement of the full spatiotemporal field of ultrashort pulses with multispectral digital holography. In PDF format).

Finally, if your pulse-measurement problem is so challenging that it'd be better classified as a difficult research problem, no problem, we're the world's leaders in pulse measurement; just let us know. You'll be surprised what we can do and how inexpensively we can do it. We are also closely tied with Prof. Rick Trebino's group at Georgia Tech, and they can solve almost any pulse-measurement problem.

To customize a measurement design, we need the following information:

• your pulse length
• wavelength
• pulse energy
• bandwidth (or expected pulse complexity)
• spatial-mode quality
• rep rate
• shot-to-shot jitter (if you desire multi-shot measurement)
• if your pulse is weak, can you provide a reference pulse of the same color?

We guarantee the simplest, least expensive, and most reliable method for your measurement problem.
