  • adj. Involving multiple photons


Sorry, no etymologies found.


  • Combining an imaging technique called multiphoton microscopy with "optical clearing," which uses a solution that renders tissue transparent, the researchers were able to scan mouse organs and create high-resolution images of the brain, small intestine, large intestine, kidney, lung and testicles.


  • Instead of using a chemical reaction that would proceed once a single photon was absorbed, they relied on molecules that had to absorb two photons at the laser's wavelength before reacting, a technique called multiphoton absorption polymerization, or MAP.

  • Eli spent a lot of his youth doing multiphoton stuff and his reaction to this test was that he was not impressed, and certainly not convinced.

    Rabett Run

  • This shows that no O(1D) the first electronically excited state which will not collisionally or radiatively quench to the ground state by collision in almost all cases was produced by multiphoton processes 7. Any ground state O(3P) would have to be improbably hot translationally to react with water vapor producing OH 8. Higher lying quartet states of NO2 are unlikely to react.

  • For molecules and multiphoton excitation MPE, one distinguishes between a simultaneous and step-wise aka sequential multiphoton excitation.

  • This is a VERY tricky thing, because you can easily do amusing multiphoton things like

  • In short, Sinha's conditions favored significant multiphoton excitation, it occured as sure as Eli likes carrots.

  • This is what happens when multiphoton excitation is used for ionization MPI.

  • Indeed, you can get very high up, even with much less energy then Sinha used, as shown by the fact that in 1983 emission was seen from the Schumann-Runge bands of O2 following focussed excitation of NO2 (open article), and there are lots of studies of multiphoton ionization following focussed laser excitation of NO2 (Ed Grant was hot on that in the 1980s).

  • While the latter pays much better, it certainly does less for the world than my previous work in biomath working on multiphoton microscopy, which is mostly used for understanding cellular activities WRT cancer.
