We report on time-resolved broadband transient reflectivity (tr-bb-TR)measurements performed on a bulk single crystal of T$_d$-MoTe$_2$ as a functionof the incident pump fluence (F). Tr-bb-TR data unveil photoinduced electronicchanges progressing on the sub-picosecond timescale as well as the dynamics ofthe coherent low-frequency $^1A_1$ interlayer shear phonon. Our resultsindicate a gradual evolution of both the TR and the $^1A_1$ Fourier intensityspectra as a function of F, ruling out the threshold-like change that has beenassociated with the ultrafast photoinduced $T_d \to 1T'$ phase transition. Wealso observe a large redshift of the $^1A_1$ Fourier spectral features, whichsuggests that large renormalization effects are taking place on interbandtransitions that are dielectrically susceptible to the $^1A_1$ interlayerphonon displacement.
