  2. Contents: Pattern and solitons in parametric wave mixing Solitons in laser with nonlinear absorber Moving solitons Simultaneous existence of larger numbers of solitons Conclusion

  3. Phase solitons in 4-wave-mixing (prediction)

  4. Phase-conjugating resonator

  5. Phase domains

  6. Dynamics of phase domains (solitons)

  7. Contraction of phase front

  8. Growing phase domains

  9. Phase fronts Fronts and solitons

  10. Coexistence of fronts and solitons

  11. 3-D Phase domains

  13. Tetraedal (diamond-) pattern

  14. Vortex rings in fast laser

  15. Self-imaging laser resonator with nonlinear elements in conjugated planes

  16. Soliton in laser with nonlinear absorber

  17. Soliton can be switched on everywhere

  18. Moving a soliton by a phase gradient

  19. Trapping a soliton by a „phase-trough“

  20. Longitudinal mode families of a plane resonator

  21. Moving solitons (schematic)

  22. Moving solitons (experiment)

  23. near field far field Moving solitons (numerical calculation)

  24. Self-imaging laser resonator with nonlinear elements in image plane

  25. Development of spatial solitons from a laser „vortex fluid“

  26. Coexisting larger numbers of solitons

  29. Conclusions: • Phase solitons exist in 4-wave-mixing resonators • Bright solitons exist in laser resonators with nonlinear absorber (competition in velocity space or coexistence of several solitons) • Applications possible for optical information processing (see paper by Larionova: Spatial Solitons in Semiconductor Microcavities)
