As the reaction caused by two-photon absorption can be limited to the small area of the focal point of a laser light, it is possible to increase the number of recording layers. The nuance is that Fujifilm has combined a two-photon absorption method with a "heat-mode recording" method.
The latter refers to technology that makes the most of a phenomenon where a change is caused by applying a laser light with a high energy density to instantaneously increase the temperature of a minute area of a recording material.
Two-photon absorption refers to the simultaneous absorption of two photons of identical or different frequencies to excite a molecule from one state to a higher energy electronic state.
