“…For the electrostatic mode, the normalized frequency of the plasma wave is always higher for the plasma with CNTs as compared to plasma without CNTs. For the normalized laser amplitude = a 0.01, 0 the growth rate in the absence of CNTs, is found to be of the order of w ´-2.7 10 .…”

“…In laser driven fusion, stimulated Raman backscattering [6,7] is a major concern as it reflects a significant fraction of laser energy before reaching the critical layer and produces hot electrons, jeopardizing the shock compression of the core. Stimulated Raman and Compton scattering from relativistic electron beams produce free electron laser (FEL) radiation up to X-ray wavelengths [8][9][10][11]. SRS is a nonlinear coherent process showing several advantages in its various applications [12].…”

Stimulated Raman scattering of a laser pump in a carbon nanotube (CNT) embedded plasma is studied. The CNT response to the laser field is anisotropic and modifies the electrostatic and electromagnetic modes significantly. For Raman backscattering, the growth rate increases due to the presence of CNTs. The enhancement is strong when frequency of the pump or one of the decay waves is near the surface plasmon resonance. Exactly at the resonance, the phase matching condition is not satisfied. For the normalized laser amplitude a0 = 0.01 at 1.06 micron wavelength, the growth time is typically in the sub-picosecond range. The linear damping of the Langmuir wave decreases the growth rate.
