A possible two-photon effect in vitro using a focused laser beam.

M W Berns
PMCID: PMC1334922  PMID: 938735

Abstract

A probable two-photon effect is described as a result of focusing an intense pulsed laser beam onto chromosomes of living cells. The effect was suggested after the derivation of a two-photon action spectrum and the demonstration of a lack of reciprocity.
