E. Louvergneaux et al., COUPLED LONGITUDINAL AND TRANSVERSE SELF-ORGANIZATION IN LASERS INDUCED BY TRANSVERSE-MODE LOCKING, Physical review. A, 57(6), 1998, pp. 4899-4904
Self-organization, resulting from the locking of two different family
eigenmodes in a CO2 laser, is investigated in a coupled longitudinal a
nd transverse approach. We show that within the near-field;region the
spatial evolution of the transverse pattern along the propagation axis
involves bistability and symmetry breaking. The dynamics of prelockin
g, already suggesting the locked pattern to come, is also described.
