  • Patent number: 12352953
    Abstract: In an example, an optical system includes a fiber, a detector, and a gradient-index (GRIN) lens assembly. The GRIN lens assembly is positioned between the fiber and the detector and couples light from an exit aperture of the fiber onto the detector. The spot size of light exiting the fiber is larger than a spot size of light exiting the GRIN lens assembly. Additionally, the spot area of light exiting the GRIN lens assembly may be smaller than a sensing area of the detector. Among other advantages, the GRIN lens assembly increases the amount of light coupled onto the detector from the fiber. Additionally, the GRIN lens assembly may make the optical system more robust against vibrations (and other factors) that change the energy distribution of light exiting the fiber.

  • Publication number: 20240167944
    Abstract: A system may include a diffraction grating, an optical detector, and multiple optical systems (e.g., at least two). The optical detector includes a detection surface configured to detect optical signals. The optical detector is positioned so the detection surface receives diffracted spectra from the diffraction grating. A first optical beam forming system directs a first optical beam towards the diffraction grating such that a diffracted spectrum of the first optical beam is received by a first portion of the detection surface of the optical detector. A second optical beam forming system (different that the first optical beam forming system) directs a second optical beam towards the diffraction grating such that a diffracted spectrum of the second optical beam is received by a second portion of the detection surface of the optical detector (e.g., different than the first portion of the detection surface).

  • Publication number: 20240039231
    Abstract: A device may include an active material, a primary optical system, and a pump optical system. The primary optical system forms a primary folded optical path through the active material for a primary optical beam. The pump optical system forms a pump folded optical path through the active material for pump light. The pump folded optical path overlaps with the primary folded optical path in the active material. The pump light propagating along the pump folded optical path pumps the active material to amplify the primary optical beam propagating through the active material along the primary folded optical path.
