Laser-induced multiphoton processes in living cells.

Abstract

It is shown that specific light-induced subcellular alterations, usually referred to as phase "paling," result from multiphoton absorption processes. For green light (532 nm), four photons are required to induce paling in chromosomes and nucleoli; a two-photon process is observed for UV light (266 nm).
