Web12 de dez. de 2024 · An electron beam at a relativistic velocity has a self-focusing effect due to the magnetic field created by the electron beam itself and the increase in electron mass, which reduces the divergence of the electron beam due to the SC effect. Therefore, the SC effect mainly occurs within the acceleration field in an electron gun.

The area of high coherence appears in the center and along two diagonal lines. With increasing turbulence, the coherence area reduces gradually along one diagonal line and is retained along the other one. WebAnother application of self-focusing is the measurement of the magnitude of the Kerr nonlinearity (→ z-scan measurements). Note that cascaded χ (2) nonlinearities (essentially, frequency doubling with subsequent backconversion) can also lead to an effective χ (3) nonlinearity, resulting either in self-focusing or (for negative effective χ (3) ) self … ct corporation colorado phone number
