Laser Position Stabilisation

The stability of the position of a laser is important to ensure accuracy. So that the laser points to where it is supposed to. A laser’s beam can move in space for various reasons, and the Photonics Technologies our Aligna or Fiberlock can help with this.

The accuracy of the laser and position stability is stated as an angular value. This value of stability measures how much the laser’s position moves from the intended target over time. This value is usually measured using milli- or microradians (mr or μr).


Laser beams, whether used in an experiment or in industrial applications, can move in space for many reasons:

If you are experiencing any of the above reasons when undertaking your experiment have a look at the products above that will help stabilise your laser beam.
