Conventional systems exploiting dynamic control of spatiotemporal beams using spatial light modulators are limited in data rate and power density. These are not the only limits, since the desired spatial control should include a continuum of Orbital Angular Momentum so that fractional and integer OAM states are possible, as well as coherent combinations to realize complex power flows for interaction science in linear and nonlinear regimes. This talk will summarize recent progress based on the spatial and dynamic control of Higher Order Bessel Gaussian Beams that can be reconfigured at unprecedented rates and applicable for high power densities. Applications will include propagation through dynamic turbulence, beam control and nonlinear interactions exploiting a continuum of OAM states. Future perspectives will also be discussed for a number of applications relevant to Maritime sensing.
