Hmm, so if I understand the paper (which I might not), the lens is created by one laser beam, and then light from the sample causes a two photon effect in the lens area. Since two photon effects continue propagation, it’s in effect a pinhole which can be used for imaging. This seems like quite an elegant experiment.
