An optical parametric oscillator and related optics:
I bought a Lytro camera, which captures the entire depth of field and allows you to refocus a picture after you take it. It accomplishes this by having a microlens array in front of the sensor, which captures information about light rays and angles in the entire field, then the image can be reconstructed in post-processing.
Here are some shots of microscopes and laser tables. Click around on the images to refocus.

P.S. Sorry I’ve been so absent. Postdoc+baby = no time for blog. :)
