  The charge-density wave (CDW) phase in the layered transition-metal
dichalcogenide VTe$_{2}$ is strongly coupled to the band inversion involving
vanadium and tellurium orbitals. In particular, this coupling leads to a
selective disappearance of the Dirac-type states that characterize the normal
phase, when the CDW phase sets in. Here, by means of broadband time-resolved
optical spectroscopy (TR-OS), we investigate the ultrafast reflectivity changes
caused by collective and single particle excitations in the CDW ground state of
VTe$_{2}$. Remarkably, our measurements show the presence of two collective
(amplitude) modes of the CDW ground state. By applying a double-pulse
excitation scheme, we show the possibility to manipulate these modes,
demonstrating a more efficient way to control and perturb the CDW phase in
VTe$_{2}$.
