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 ...

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 ...

As two-photon processes are nonlinear and require high-optical intensities to occur, they typically only take place at the focal spot of a light beam. This characteristic offers the ability to ...

Two-photon vision is a novel method with great potential ... Brightness also depends on the focus of the beam on the observer's retina—the received stimuli are sharper and have better contrast ...

This breakthrough in quantum physics introduces a cutting-edge device called a frequency beam ... two frequencies. This breakthrough has enabled the successful generation of a two-photon NOON ...

The technique relies on transmission measurements made at two photon energies to allow calcium ... BMD techniques were originally based on single-photon absorptiometry, in which transmission of a ...

Photon profilers analyze beam parameters, including the beam's profile, size, position, and M² of lasers and optics in manufacturing and R&D. People come to us because they trust Photon to help with ...
