Discussion

Computational study reveals different plasma channel behaviors for resonant and sub-resonant laser wavelengths in rubidium vapor.

Distinct behavior in plasma channel creation occurs at 780 nm versus 810 nm laser pulses, and pulse wavelengths affect self-focusing significantly.
Pulse wavelengths below the resonance lead to strong self-focusing, while those above yield weaker effects, highlighting the role of dispersion.
Computation shows the resonance interaction is paramount, with varying multiphoton ionization rates influencing the overall dynamics.
The study emphasizes the interplay of parameters like dispersion and ionization in shaping the propagation characteristics of laser pulses.
