APPARATUS AND METHOD FOR POLARIZING A LASER BEAM HAVING AN UNDEFINED POLARIZATION STATE AND LASER MACHINING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033851 titled 'APPARATUS AND METHOD FOR POLARIZING A LASER BEAM HAVING AN UNDEFINED POLARIZATION STATE AND LASER MACHINING SYSTEM

Simplified Explanation

The patent application describes an apparatus for polarizing an input laser beam with an undefined polarization state. The apparatus includes a beam splitting device that splits the input laser beam into two component beams with defined polarization states. A polarization changing element is used to change the polarization state of one of the component beams so that both component beams have the same defined polarization state. A focusing element then combines the component beams into an output laser beam while maintaining the defined polarization state.

  • The apparatus splits an input laser beam into two component beams with defined polarization states.
  • One of the component beams has its polarization state changed to match the other component beam.
  • The component beams are then combined into an output laser beam while maintaining the defined polarization state.

Potential applications of this technology:

  • Laser machining systems
  • Laser cutting and engraving
  • Laser welding
  • Laser drilling

Problems solved by this technology:

  • Polarizing an input laser beam with an undefined polarization state
  • Ensuring both component beams have the same defined polarization state

Benefits of this technology:

  • Improved precision and accuracy in laser machining processes
  • Enhanced control over the polarization state of the output laser beam
  • Increased efficiency and effectiveness in laser-based applications


Original Abstract Submitted

an apparatus for polarizing an input laser beam having an undefined polarization state includes a beam splitting device for splitting the input laser beam into a first component beam having a first defined polarization state and a second component beam having a second defined polarization state. a polarization changing element changes the polarization state of one of the polarized component beams, with the result that both component beams have the same defined polarization state. a focusing element is configured to input couple both component beams into a light-guiding element in order to combine the component beams to form an output laser beam while maintaining the defined polarization state. a laser machining system including the apparatus and a method for polarizing an unpolarized laser beam, are also provided.
