[edit] Extent of resolution improvement

I think the article would benefit if it's easy to add an example of the improvement of resolution, particularly z-direction over single-photon excitation, and comparison with confocal and other techniques.--Skoch3 03:28, 10 February 2007 (UTC)

i don't believe that z-resolution with multiphoton microscopy is improved. it should be somewhat worse, given that the the z-resolution is inversely related to the excitation wavelength. i believe it's roughly on the order of being 2x worse in the z-axis. i forget the details, but i believe you're correct in that this may be an important point to note.--cpschultz 01:20, 28 March 2007 (UTC)

[edit] energy conservation

how can two photons of 1/2E add up to be slightly more than E? should include explanation of this. —The preceding unsigned comment was added by 141.213.67.55 (talk) 21:16, 20 February 2007 (UTC).
