What does m2 mean in Laser Science?
In laser science, the parameter M2, 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.
What is the M2 factor?
The M 2 factor, also called beam quality factor or beam propagation factor, is a common measure of the beam quality of a laser beam. According to ISO Standard 11146 [4], it is defined as the beam parameter product divided by λ / π , the latter being the beam parameter product for a diffraction-limited Gaussian beam with the same wavelength .
What is the best m2 for laser beam quality?
In fact, the best possible result is M 2 = 1, and as the value of M 2 increases, the quality of the laser decreases. Why is it important to know the beam quality of your laser? Once the M 2 factor is defined, it is possible to inject it back into the equations for generalized Gaussian beam propagation.
What is the M2 factor of TEM 00 laser beams?
Collimated TEM 00 diode laser beams usually have an M2 ranging from 1.1 to 1.7. For high-energy multimode lasers, the M2 factor can be as high as 3 or 4. In all cases, the M 2 factor, which varies significantly, affects the characteristics of a laser beam and cannot be neglected in optical designs.
