Thin disk pump optics for guiding up to 3 kW of pump power multiple times over a laser active thin disk medium, such as provided by our TD12 or TD20  disks.



  • Can be operated with a pump power of up to 3 kW
  • For laser disks with a free aperture of up to 14 mm and pump spot diameters of up to 12 mm when using TD20 (TD12 is optionally able to be installed)
  • For guiding the pump light with 48 passes over the laser disk;
  • The pump power should be delivered in fibers. Interfaces for common fiber connectors are available. In a special version up to three fibers can be applied
  • Water cooled frame and optics
  • Symmetrical cooling to avoid thermal misalignment
  • Inclusive collimation and fiber connector for one fiber
  • Laboratory version for R&D
