Pulse chirping effect on controlling the transverse cavity oscillations in nonlinear bubble regime |
(color online) The electron density at the pulse head of: (a) the negatively chirped pulse, (b) the positively chirped pulse, when propagating through the under-dense plasma (n e = 0.02n c) at the times of t = 300 fs, t = 500 fs, and t = 600 fs. |
