This chapter first reviews the main properties of laser solitons (LS) in the vertical-cavity surface-emitting laser (VCSEL) with frequency-selective feedback (FSF). It explores more complex phenomena related to the Goldstone modes and how LS interact with imperfections due to spatial disorder. The chapter then presents evidence of the dispersive mechanism at the base of the existence of LS followed by the relevance of spatial disorder in pinning LS to preferred positions. Next, it shows that the experimental observations are different as the LS are pinned by disorder. This leads to frequency- and phase-locking between LS at different locations. The chapter looks at the transient switch-on dynamics of LS as well as giving an outlook on asymptotic dynamic states. Finally, it shows that solitons can operate on multiple longitudinal cavity modes and demonstrates self-pulsing indicating that these modes are at least partially phase-locked.
