Spontaneous Polarization Experimental Apparatus

Composite Visible Color + Infrared Photos

The first photograph shows (nearly) the entire cesium spontaneous polarization experiment, from the cesium cell inside the Helmholtz coils at left over to the 894 nm pump laser at the right rear of the optical table. The second photo is a close-up of the right side of the first photo, showing the polarization modulators, wavemeter, beam shaping optics, and the lasers. (The diagram below the photos is taken from my final exam talk, and it should clear up what items are seen in the photos.) Each photo is a composite of a visible color photo and an infrared black&white photo, so that the normally invisible 894 and 852 nm laser beams can be seen. The film was switched from color to infrared without moving the camera, and the separate negatives were later composited in the darkroom to create a single print.  (Photographs © 1997 Beverly Multerer Photography)
