With the development of laser technology, laser application technology increasingly plays a leading role in the field of industry. High power laser products and their safety requirements are attracting more attention. In laser industrial applications, laser beam quality and the system of laser beam propagation and focusing are greatly ignored. Furthermore, the basic safety standards for laser products have been neither widely publicized nor strictly enforced because of rapid development. This paper examines the underlying relationship between laser beam quality and laser manufacturing, and makes a comparison among different laser systems. It is also shown how the laser safety standards could be better understood and laser beam quality standard is advocated that directly relates to a mission requirement.
