Abstract

A hand-held laser weapon including: a laser module for generating a laser light; a telescope module fiber optically coupled to the laser module for focusing the laser light on a target; a burst power module, including a storage capacitor, for storing electrical energy capable of a rapid release in the form of a current; a trickle power module including a battery for providing said electrical energy to the burst power module; a drive circuit for driving the laser module with the stored electrical energy to generate the laser light; a trigger module for providing the stored electrical energy to the drive circuit; and a structure for coupling at least the laser module, the telescope module, the drive circuit and the trigger module together.

Claims (25)
