Things to know

We talk straight. Nevertheless, the use of technical terms is unavoidable. Here you will find the most important terms.

Fiber-coupled Diode Lasers

In many cases, it is convenient to couple the output of a laser diode into an optical fiber in order to deliver the light to the place where it is needed. Fiber-coupled (also called fiber-integrated) diode lasers have several advantages:

  • The light exiting the fiber has a circular and smooth (homogenized) intensity profile and a symmetric beam quality, which is in many cases very convenient. For example, less sophisticated optics are required for generating a circular pump spot for an end-pumped solid-state laser.
  • It becomes possible to remove the laser diodes together with their cooling arrangements e.g. from a solid-state laser head, which can then be more compact, and more space is left for other parts at this place.
  • Defective fiber-coupled diode lasers can easily be replaced without changing the alignment of the device where the light is used.
  • Fiber-coupled devices can be easily combined with other fiber-optic components.
