Testimonials from Our Customers

We value what our customers think of us and our products. Here are what some of them have shared.


We’ve been operating a Swamp Optics Grenouille 8-20-USB unit at Davidson College for several years; the unit is very helpful in teaching our students about ultrafast pulses and the uncertainty principle. Our students can operate the Grenouille successfully by their third semester of undergraduate physics. We recently developed a problem with the software freezing up.  We sent a note to customer service around late one night and got a response in less than an hour!  Swamp Optics provided us with a clean re-install of the software, and all works great again.  Kudos to Swamp Optics for an incredibly rapid response!

We’ve been operating a Swamp Optics Grenouille 15-100-USB unit at University of Southern California for several years. This unit is very helpful in many of our research projects for getting the pulse information for ultrafast laser systems. This unit is very easy to learn to operate (usually take 10 mins to set it up), and the software is clear to read. When saving documents, it gives full information such as temporal/spectral pulse shape and phase info. as well as field info. We recently had a problem in coupling a dispersed beam in, and we sent a note at their website. We got the extreme professional feedback in half a day, and the engineer even had a conference call with us for a live demo and problem solving, after which we worked well again with the unit. Many thanks to Swamp Optics for their timely and professional response and help!

We bought a Swamp Optics Grenouille 8-20 USB mainly for a 1-day lab course in ultrashort optics. The students should learn about the effects of different optical elements on ultrashort pulses. The setup of the Grenouille is so easy, that students, which never worked in a laser lab, can set the device up and measure different beam paths independent from the supervisor. The advantages of the Grenouille also enables us to teach about spatial chirp and pulse front tilt, which is often neglected, but not less important. This success also led us to use the Grenouille in our research labs. We were measuring on a Saturday evening and wrote an email to the Swamp Optics support team to get some tips to improve our data quality. They not only answered within a couple of hours but also provided very useful tips, that helped us to improve the measurement signal significantly. This device showed for our usage in ultrafast solid-state spectroscopy and high harmonic radiation a broad range of advantages compared to autocorrelators and conventional FROG. It evolved to our go-to measurement device for pulse characterization.

The FROG support team replies quickly, helpfully, and kindly.  Don't hesitate in contacting them for assistance; being fellow researchers, they understand the plagues of the laboratory...such as the apparatus manual suddenly disappearing."
