The active medium in the laser (such as gas, solid, or semiconductor) has an energy level structure comprising a higher energy level (excited state) and a lower energy level (ground state). The energy difference between these levels determines the wavelength and characteristics of the laser.

In laser welding processes, shielding gas plays a crucial role in protecting the weld area from atmospheric contaminants and oxidation. Here are key considerations regarding shielding gas in laser welding:

In laser welding processes, the focal distance (also known as standoff distance) is a crucial parameter. It refers to the distance between the welding head (or laser spot) and the surface of the workpiece, typically defined as the focal length of the welding optics to the workpiece surface. This distance selection significantly impacts the distribution of energy density, formation of the weld pool, and weld seam quality during the welding process.
