Opto-thermal laser detonator
Abstract
An opto-thermal laser detonator uses resonantly absorptive tuned nano-material associated with secondary explosives for optical absorption and initiation by an integral laser diode. The opto-thermal laser detonator includes main explosive material; resonantly absorptive tuned nano-material; secondary explosive material, wherein the resonantly absorptive tuned nano-material and the secondary explosive material are associated to form associated material made of the resonantly absorptive tuned nano-material and the secondary explosive material; and a laser diode operatively connected to the associated material, wherein the laser diode initiates the associated material which in turn initiates the main explosive material.
