We investigate the dependence of Cherenkov radiation (CR) on pump pulse parameters and its evolution along the propagation distance. Using a Ti:sapphire laser emitting 10 fs pulses as the pump source, we demonstrate highly efficient (>40%), broadband (>50 nm) CR in the visible-wavelength range with a threshold energy less than 100 pJ and a tuning range over 100 nm.
