Takuya TAKASAKI 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).

  • Laser amplification device
    Patent number: 9698556
    Abstract: Plural signal beams enter a planar waveguide laser amplifier from different directions to follow different paths therein, which reduces a region not contributing to amplification where no signal beam passes. Plural signal beams follow different paths in the planar waveguide, and a second signal beam utilizes the gain of a portion of the planar waveguide that a first signal beam cannot utilize. By this configuration, a region not contributing to amplification of the signal beams in the planar waveguide laser amplifier can be reduced, causing to efficiently amplify plural signal beams.
    Type: Grant
