Schemes of electrons dynamics adjusted by shaped femtosecond laser pulses. Electric fields of the applied laser pulse and time-dependent excited electrons of diamond with different (a) pulse delays99 and (b) sub-pulse numbers99. (c) Electric fields of the applied laser pulse (top panel) and the electron density change of diamond from that in the ground state after laser termination with different pulse energy ratios99. (d) Time-dependent electron temperature of fused silica with different pulse dual-wavelengths111.
