In laser science, laser beam quality defines aspects of the beam illumination pattern and the merits of a particular laser beam's propagation and transformation properties. By observing and recording

In optics, any optical instrument or system—a microscope, telescope, or camera—has a principal limit to its resolution due to the physics of diffraction. An optical instrument is said to be diffractio
Laser beam quality
…or not the beam is being clipped by an obstruction; By focusing the laser beam with a lens and measuring the minimum spot size, the number of times diffraction limit or focusing quality can be computed. Laser beam quality studies commenced in the 1960s, following the discovery of the laser. The M (mode) factor was…
