Pulsed second harmonic generation in plasma with a magnetic wiggler

Harsha Jaloree J.Parashar


Magnetic wiggler assisted phase matched second harmonic of a Gaussian laser pulse in a plasma is studied.  The wiggler provides additional momentum required for phase matching, however this is only for a particular instant. The required wiggler wave number increases with pulse duration and plasma density. The efficiency of the process drops sharply away from the phase matching instant.
