Abstract
It is shown that the size of the focal spot has a substantial influence on the dynamics of Mandel'shtam-Brillouin induced scattering (MBIS) for the la ser beam power near critical for striction self-focusing. For small focal s pots MBIS suppresses self-focusing. An increase in the size of the focal sp ot leads to growth of the MBIS pulsations and the steady-state setup time. For large enough focal spots MBIS arises in the form of regular intense spi kes. Physical processes shaping the dynamics of MBIS are discussed. (C) 199 9 American Institute of Physics.
