A guide on laser beam quality and M2 measurement
In this guide, we will introduce you to the concept of laser beam quality measurement with the M2 parameter, which quantifies the laser beam quality, and how to measure M2 for a real laser.

M² and Beam Quality Parameters — laserbeamsize 2.4.1 documentation
Since the gain medium in a diode laser usually has a rectangular cross section, there are two different minimum beam radii associated with the exit aperture. These are often assumed to correspond to the
Laser Diode Application Note
The M squared Laser Beam models a laser based on its M2 factor, also known as beam quality or beam propagation factor. The smallest possible value of M2 is 1, and this specifies a Gaussian TEM 00 beam.
M2 Factor – M squared, laser beam, quality factor, beam divergence
The M 2 factor determines how tightly a laser beam can be focused to a small spot and is crucial for determining the brightness (radiance) of the beam. For a given beam waist radius, the beam

Beam Quality and Strehl Ratio
The M 2 factor is important because it represents how well a laser beam can be focused for a given divergence. Lower M 2 factors correspond with a tighter focus, a more efficient use of the power
M2 Factor (Quality Factor)
To accommodate this variance, a quality factor, M 2 (called the “M-square” factor), has been defined to describe the deviation of the laser beam from a theoretical Gaussian.
M squared
It relates the beam divergence of a laser beam to the minimum focussed spot size that can be achieved. For a single mode TEM 00 (Gaussian) laser beam, M 2 is exactly one.
M squared
In laser science, the parameter M, also known as the beam propagation ratio or beam quality factor is a measure of laser beam quality. It represents the degree of variation of a beam from an ideal Gaussian beam. It is calculated from the ratio of the beam parameter product (BPP) of the beam to that of a Gaussian beam with the same wavelength. It relates the beam divergence of a laser beam to the minimum focussed spot size that can be achieved. For a single mode TEM00 (Gaussian) laser beam,
