  • Light source device, direct diode laser system, and optical coupling device
    Patent number: 11579384
    Abstract: A light source device includes an optical fiber; a beam light source configured to coaxially combine laser beams of different peak wavelengths to generate and emit a wavelength-combined beam; and an optical coupling device configured to allow the wavelength-combined beam emitted from the beam light source to be incident on the optical fiber. The optical coupling device includes a first cylindrical lens configured to focus the wavelength-combined beam in a first plane and having a first focal length, a second cylindrical lens configured to focus the wavelength-combined beam in a second plane and having a second focal length, and a third cylindrical lens having a third focal length greater than the first focal length and configured to focus the wavelength-combined beam in the first plane to be incident on the first cylindrical lens.

  • Light source device and external cavity laser module
    Patent number: 11387623
    Abstract: An external cavity laser module is configured to emit a laser beam and includes: a collimation laser light source having a Littrow configuration; a diffraction grating configured to selectively reflect and transmit light of a specific wavelength; a support member supporting the collimation laser light source and the diffraction grating; and a base rotatably supporting the support member to correct an axial direction of the laser beam emitted from the external cavity laser module.
