Ask RP Photonics for advice on how to measure the beam quality of your laser source, or how to optimize it, e.g. via advanced resonator design.Author: the photonics expert Dr. Rüdiger Paschotta (RP)Definition: beams with a minimum possible beam divergence for a given waist radius Category...
Figure 2 shows the beam quality factor M2 of coherent supergaussian beams with flat phase front as a function of the supergaussian order. The more we approximate a rectangular profile with a high beam order, the worse is the beam quality; the M2 factor rises with no limit (and eventually ...
Together with the optical power, the beam quality factor determines the brightness (more precisely, the radiance) of a laser beam. https://www.rp-photonics.com/m2_factor.html Rayleigh Length The Rayleigh length (or Rayleigh range) of a laser beam is the distance from the beam waist (in ...

Accurate evaluation of the intensity distribution around the focal point is necessary not only for an accurate determination of the spot size, but also for understanding the quality of the beam and the focusing elements used in particular experiments. The exact beam shape should also be qualified ...
Ask RP Photonics for advice on the origin of beam pointing fluctuations and their reduction with suitable laser designs or with feedback stabilization. With the powerful RP Resonator software one can calculate how misalignments of mirrors cause beam pointing deviations.Author...
