The possibility of initiating a charge of a light-sensitive high-energy mercury(II) perchlorate complex with a 1-H-5-hydrazinotetrazole ligand by a laser diode beam (λ = 445 nm) has been studied for the first time. It is established that this radiation induces an explosion in the high-energy VS-2 composition based on the mercury complex composition with an optically transparent polymer. The initiation threshold and ignition delay time of VS-2 have been studied as functions of the laser beam energy. A mechanism of laser initiation of the mercury perchlorate complex is proposed.
