Does the excitation wavelength affect the ultrafast quenching dynamics of the charge-density wave in 1 T -TiSe 2 ?

The ultrafast spectral responses of a charge-ordered state in 1 T -TiSe 2 to the photo-excitation with laser-pulses of 790 nm and 395 nm center wavelength are compared. Time- and angle-resolved photoemission reveals pronounced differences in the energy-momentum distribution of the nascent electron gas; a distinct effect of the distribution character on the destruction dynamics of the charge-ordered state is, however, not observed.
