Frank Massmann 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).

  • Converter device and irradiation device having such a converter device
    Patent number: 10788196
    Abstract: According to the present disclosure, a converter device is provided. The device includes a phosphor element for converting a pump radiation into a conversion radiation and an excitation coil for producing an alternating magnetic field in which the phosphor element is arranged. The phosphor element has a conductor loop forming a coupling coil that is inductively coupled to the excitation coil such that the coupling coil and hence the phosphor element can be monitored by way of the inductive coupling.
    Type: Grant

  • Pump arrangement for transversally pumping an active medium
    Patent number: 7266138
    Abstract: The invention relates to a pump arrangement for transversally pumping an active medium, especially a laser rod, wherein two pump light sources are arranged on a plane perpendicular to the longitudinal axis of the active medium, especially pertaining to the laser rod. The value of the smallest angle between the central axes of the pump light sources is less than 180°. A pump arrangement is also provided which illuminates the active medium in a particularly uniform manner.
