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.
Claims4
An opto-thermal laser detonation method, comprising the steps of:
- providing main explosive material;
- providing resonantly absorptive tuned nano-material;
- providing secondary explosive material;
- associating said resonantly absorptive tuned nano-material with said secondary explosive material providing associated material made of said resonantly absorptive tuned nano-material and said secondary explosive material;
- positioning said associated material in said main explosive material;
- providing an output pellet;
- providing a laser diode that produces laser radiation;
- locating said laser diode in said explosive material and in said associated material, positioning said lens to receive said laser radiation and project said laser radiation to said associated material,
- positioning said output pellet proximate said associated material;
