I couldn't find any photograph or diagram of the device that generate the numbers in the web page. I worked with optic tables, and I'm just curious and want more details.

I only found the preprint: http://arxiv.org/abs/1107.4438 , so they use an 1550 nm infrared laser. The preprint has a diagram, but no photographs.

This link has some slideshow thing: (http://photonics.anu.edu.au/qoptics/index.php)

Here's a higer level link with an image (http://www.acqao.org/gallery.htm)

And here's something about quantum memory: (http://www.cqc2t.org/facilities/unsw/anu/qml)

I have founded the slideshow before, but I didn't see the gallery. Some interesting images from the gallery:

http://www.acqao.org/images/gallery/ANU_squeezing_lab.jpg : I think that this image is from another experiment. It has the light paths marked. I'd like to see something like this for this experiment. It looks like a mess, but each one of those things are bolted to the table and then carefully aligned.

http://www.acqao.org/images/gallery/ANU_QO_lab.jpg : From another experiment with visible light, probably a green 532 nm laser. It's difficult to guess the path of the light, but the image is nicer. In this image is easier to see the how the things are bolted to the table.
