Pulse chirping effect on controlling the transverse cavity oscillations in nonlinear bubble regime |
(color online) (a) The excited wake field behind the un-chirped pulse, (b) The excited density spike at the pulse head of the un-chirped laser pulse when it propagates through the under-dense plasma (n e = 0.02n c) at the times of t = 300 fs, t = 500 fs, and t = 600 fs. |
