how can i create a visual representation of quantum tunnelling on a home projector using an rb‑87 cold atom setup?

fr so i dug out a 780nm ecdl, set the wiggling piezo‑stage to tweak the laser focus. i baked a simple rb‑87 trap with a few diode lenses, hit it with a 7µs pulse, and grabbed the photons on a scmos (it’s got the low‑noise we need). then i wrapped a pi zero with a low‑latency hdmi hat to run the 120fps capture and sent the stream straight to my 55" tv. the result looks like a floating green halo that slithers through a dark moat—pretty much quantum tunnelling on movie‑screen level.

technical bits if you want a cheat sheet:

• diode laser (external cavity, 78.0–78.0 ghz offset)
• 75 v piezo drive (20 khz bandwidth, <0.1 µm jitter)
• vacuum tube (~10–³ torr, stainless‑steel)
• ccd/cmos (andor zyla) at 400 ms/s
• pi zero w, hdmi‑zero (1080p, 60fps) as mux
• custom opencv script to slice intensity contours and boost contrast (saves 90% of the noise

this set‑up won me an extra 700 hrs of “eerie” movie time tonight. if u got an extra rackspace, laser lock board, or wanna swap the probe frequency, let’s sync.

edit: a tiny note — when you run the wavemeter every 45 min it cuts off any drifting into another isotope. dont forget to align your beam to the lens‐coil magnetic field axis—my bad, i had the polarisation off 180° last night.

bigger aim? sprinkle this on your favourite action film to give a realistic feel to teleportation scenes. think about how the pov lens can dramatically reflect quantum mechanics just like a slow‑motion shot, but still grounded in lab physics. drop any questions or tweak ideas. cheers
