The technology is based on two-photon absorption; when the beam of an ultrafast (for example, femtosecond) laser is tightly focused on a volume of photosensitive material, the polymerization ...

In recent years, development of the two-photon absorption process for optical data storage has made significant progress. Call/Recall researchers have succeeded in storing the equivalent of 200 ...

Multiphoton microscopy (MPM) is a powerful imaging technique widely used in biological and biomedical research.

A research group led by Dr. Toru Ube at Chuo University enabled 3D-selective deformation of “photomobile polymer materials” ...

The average laser power used ranges from 3mW for small knots to 13 mW for larger ones, as measured just before the objective (note that the power in the sample is further reduced by about a factor of ...

Two-photon laser direct writing lithography or ... in this research effectively separates the processes of light absorption ...
