OSTI ID:7192532
The convective parametric decay of an incident electromagnetic wave (..omega../sub 0/,k/sub 0/) into two plasmons at ..omega.. = ..omega../sub p/ in a slightly inhomogeneous plasma of scale length L is considered. Asymptotic solutions for the fields are obtained which show that for L/lambda/sub 0/ much greater than (..omega../sub p/lambda/sub D//..nu..lambda/sub 0/)/sup 2/, where ..nu.. is the plasmon damping rate, the homogeneous-plasma decay criterion must be satisfied by the pump field for instability.
