April Fools Ion

Despite the lockdown, some trapping in the lab this week. First single-ion experiments this year, after the 405 nm laser broke in January. Not much going on in these videos, but at least it's a single ion!

Sigma=60 Hz for the AOM frequency, so FWHM ~120 Hz AOM, and FWHM 240 Hz optical.

First clock-transition linewidth measurement give about a 200 Hz wide transition, so around 5e-13 fractionally.
