The stability of solitary waves for nonlinear Schrödinger equations with inhomogenous nonlinearities was discussed. As solitary waves are strongly unstable it was not possible to realize stable high-power propagation in a homogenous bulk media. It was suggested that stable high-power propagation could be achieved in plasma by sending a laser beam that created a channel with a reduced electron density.
