This energy is released as a photon. The energy of the photon can be worked out using the equation If an electron moves from level \(E_{2}\) to \(E_{1}\) the energy of the photon can be worked out ...
allowing multi-photon absorption. Optical poling of a glass material: By irradiating two laser beams the randomness of a dye in a glass matrix could be changed to an ordered direction. By this ...
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 ...
