Patents by Inventor Titus A. Casazza

Titus A. Casazza has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7239655
    Abstract: A compact high power laser dazzling device includes at least one heat sink, multiple laser resonators and an optical head. Each of the laser resonators extends axially from a first end, fixedly mounted to the heat sink, to a second end emitting an individual laser beam. The optical head is disposed adjacent to the second ends of the laser resonators and includes an optical transmission assembly that directs the individual laser beams of the laser resonators to define a region of overlap at a remote point a predetermined distance from the optical head. A laser beam intensity adjuster assembly may be disposed adjacent the output end of the optical head. The laser beam intensity adjuster assembly includes a front face having multiple apertures. At least one of the apertures has a holographic diffuser element mounted therein and at least one of the apertures has an optically clear window element or no optical elements mounted therein.

  • Patent number: 6799868
    Abstract: A laser flashlight employs an emitter disposed within a housing for emitting a coherent light beam having a gaussian spatial profile along an optical axis toward the exit face of the housing. An optical system disposed within the housing intermediate the emitter and the exit face of the housing includes a laser element pumped by the emitter, a frequency/wavelength converter, and a resonator, to form the coherent light into a laser beam. A beam expander receives the laser beam, disperses the laser beam, and transmits the dispersed laser beam from the light emitting end of the housing into the ambient environment.

  • Patent number: 6431732
    Abstract: A laser flashlight employs a laser emitter disposed within a housing for emitting a coherent light along an optical axis toward the light emitting end of the housing. A power supply selectively applies electricity from a battery pack disposed within the housing to the laser emitter. An optical system disposed within the housing intermediate the laser emitter and the light emitting end of the housing includes a laser element pumped by the laser emitter, a frequency/wavelength converter, and a resonator, to form the coherent light into a laser beam. A beam expander receives the laser beam, disperses the laser beam, and transmits the dispersed laser beam from the light emitting end of the housing into the ambient environment. The dispersion of the laser beam is such that the laser beam is safe for the human eye at the light emitting end of the housing.
