Thermally induced self-focusing of a laser beam possessing spatial and temporal inhomogeneity
A. I. Erokhin, N. V. Morachevskiĭ, F. S. Faĭzullov
Abstract:
The results are presented of an experimental investigation into the effect of thermally induced nonlinear refraction on the energy distribution in the beam of a neodymium laser operating in the free-lasing regime. It is shown that, as a result of nonlinear conversion, an energy distribution at the focus of a lens which possesses strong spatial and temporal inhomogeneity is converted into a smooth distribution, close to Gaussian. The mechanism for this conversion is discussed in terms of the successive effects on the medium of the radiation in different plane-resonator oscillation modes. It is suggested that this effect can be used in laser materials-processing technology.
