i beam with high quality for

A very high (close to diffraction-limited) beam quality, associated with a high spatial coherence, is often required for interferometers, optical data recording, laser microscopy, and the like. Mode-locked lasers always have to have a high beam quality, since the excitation of higher-order transverse modes would disturb the pulse formation process.

Laser beam quality - Wikipedia

While a high-quality single-mode Gaussian beam (M 2 close to unity) is optimum for many applications, for other applications a uniform multimode tophat beam intensity distribution is required. An example is laser surgery. Power-in-the-bucket and Strehl ratio are two other attempts to define beam quality.

Beam Quality and Determination of M^2

Background. The design of optical delivery systems for laser systems is highly dependent on the laser's beam quality. The beam quality, given by the parameter M 2, ranges from 1 for a diffraction-limited TEM 00 laser beam, to several hundred for a distorted, poor quality beam. The National Institute for Standards and Technology (NIST) and the International Standards Organization (ISO) are in ...

M squared - Wikipedia

In laser science, the parameter M 2, also known as the beam quality factor, 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.

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.
