Abstract
We demonstrate enhanced axial confinement in a temporal focusing setup with a shaped spectrum and a narrow emission filter, achieving a reduction of 1 order of magnitude of the out-of-focus background when compared with conventional point-scanning two-photon microscopy. By rejecting the background in the optical domain, our technique circumvents the noise problems common in other background subtraction techniques.
