It's 49% off! And even more off from the original price.
What does it do?
Generates an arbitrary waveform when triggered, and drives a 2-stage
e/o modulator that was mounted inside. It was used in the NIF fusion
system.
I'm sure the e/o modulator is not inside that one; it's too valuable.

We made the arb waveform by summing 120 Gaussian impuses spaced 250 ps
apart. You can see the Gibbs Ears in the white waveform.

World-class to e-waste in about 20 years.
What’s the wavelength? I might be interested.
