It’s not the appearance but the parameters that determine whether a laser is good or not. Laser sounds sci-fi, yet it has long been integrated into our daily lives: Metal cutting in factories, logo marking on the back of mobile phones, myopia surgery in hospitals, and data transmission via optical fiber broadband—all of these rely on lasers. So here comes the question: How exactly do we evaluate the performance of a laser? Today, we will break down the 7 most critical parameter indicators of a laser.

Laser cutting is one of the most efficient methods for stainless steel processing, offering advantages such as high precision, smooth cut edges, and high production efficiency. However, in actual production, manufacturers often encounter various cutting defects — ranging from burrs and rough cut edges to incomplete cutting or excessive melting. These issues are closely related to key process parameters including cutting speed, laser power, focus position, and auxiliary gas pressure.

During operation, when electrical energy or other forms of energy are converted into light energy in a laser, a large amount of heat is inevitably generated. If such heat cannot be dissipated timely and effectively, the temperature of the laser will rise, which will adversely affect its output power, beam quality and wavelength stability. In severe cases, the laser chip and internal optical components may even be damaged. Therefore, efficient and reliable heat dissipation is one of the key technologies to ensure stable performance and extend the service life of lasers. With the continuous increase of laser power and the expansion of application fields, heat dissipation technologies are also undergoing continuous development and innovation. This paper introduces the main heat dissipation methods for lasers and their characteristics.

There are no shortcuts to cleaning anilox rolls. Strict and routine cleaning must begin from the first use of a new roll and be performed in accordance with regulations and procedures. Once water-based ink dries inside the cells, dissolving and removing the resin becomes an extremely difficult restoration process. It can only be achieved with great difficulty using a combination of chemical and physical methods, and this process can easily cause irreparable damage to the anilox roll.
