In this paper, we demonstrate an underwater optical communication link using an Ince-Gaussian beam which is generated by pumping a nonlinear crystal with a coherently coupled Orbital Angular Momentum (CCOAM) beam. By modulating data on the relative phase of the pump beam, a power scalable underwater communication link at 25 Gbit/s is experimentally verified for turbid coastal conditions.
