Abstract
A device for producing a laser beam or discharge. The device is constructed to be portable having a pistol grip. The laser beam is generated in the body or barrel of the device. A neodymium (Nd:YAG) rod or similar material is within a xenon flash tube to which a voltage is applied. A photon emission source is provided at one end of the (Nd:YAG) rod embodying a diode and a parabolic reflector system associated with a polarized mirror which is partly reflective and which in part transmits energy rays. A polarized optical mirror is provided at the opposite end of the (Nd:YAG) rod. Activation of atoms within the rod is initiated within the contents of an optical or resonant cavity providing a means by which the necessary excitation of atoms within the optical active (Nd:YAG) rod can be achieved in order to initiate an elevation in population and subsequent inversion of levels, near and over the threshold value necessary to generate a laser beam and the subsequent discharge of said beam. Heat dissipating means are provided including nylon phenolic quartz acrylic compound constructed to have a heat transfer gradient. Embedded in the compound is heat transfer means provided by longitudina…
