Patents by Inventor Alexei Tikhomirov

Alexei Tikhomirov 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).

  • Opto-acoustic pressure sensor
    Patent number: 8200050
    Abstract: A device (10) for sensing an acoustic signal is described. The device includes a flexible portion (14) including a laser active region (13) whose emitted wavelength varies according to a mechanical force acting on the flexible portion (14) and a flexible support member (24) operable to flex or bend according to the acoustic signal. The flexible portion (14) is coupled with the support member (24) so as to cause the flexible portion to flex or bend in accordance with the support member (24) thereby changing the emitted wavelength of the laser active region (13) of the flexible portion (14).
    Type: Grant

  • Method and apparatus for modifying out of band reflection for a laser element
    Patent number: 7848380
    Abstract: A method and apparatus for modifying the out of band reflection of a laser element is described. The laser element includes an active medium excited by optical pumping means to produce stimulation emission of light. The laser element further includes a Bragg grating structure for providing optical feedback for the active medium, with the Bragg grating structure including a phase transition region providing a change in phase. The change in phase of the phase transition region is adjusted to modify out of band reflection of said laser element.

  • Ophthalmic laser system
    Patent number: 7033346
    Abstract: An ophthalmic laser system (1) for performing procedures such as Retinal Photocoagulation and Laser Trabeculoplasty comprises a delivery module (2) and a console module (3). The console module includes a treatment laser and optical elements for directing output from the treatment laser to an optical fiber (16), which is substantially enclosed within the delivery module. The delivery module includes a slit lamp tower (6), viewing microscope (4) and alignment optics for directing and focusing output from the optical fiber to a patient treatment zone.
