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 ...

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

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

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 ...
