Abstract :

The relativistic effect of self-focusing on the second-harmonic generation of a chirped pulse laser in a preformed plasma channel has been studied. Self-focusing of the fundamental laser pulse enhances the intensity of the second harmonic pulse. Wiggler magnetic field also plays an important role in the enhancement of the efficiency of the second harmonic generation. The effect becomes more pronounced as the plasma density increases. Also effect of cold quantum plasma in the enhancement of second harmonic generation can be noticed. The present work may have very valuable applications in the field of laser driven accelerators, laser driven fusion, etc.
