A novel mechanism of low-threshold absolute parametric decay instability of a wave beam

A novel mechanism of low-threshold absolute parametric decay instability of a wave beam

A novel mechanism capable of the excitation of low-threshold absolute parametric decay instability of a pump wave in inhomogeneous plasma is proposed and analysed both analytically and numerically.
