Iranian Experts Make 20-kW Fiber Laser Source for Laser Welding

Among the achievements of the knowledge-based Iranian company are manufacturing of femtosecond lasers, modular lasers up to 6 kW power, engraving lasers up to 150 W power, single module lasers of over 2 KW power, robotic welding lasers up to 6 kW power, machine laser welding up to 4 kW power, manual laser welding machine up to 2 kW, and lasers for cleaning and removing surface fats, etc.

The 20-kW fiber laser is known as one of the most powerful industrial lasers used in various industries. These lasers with very high output power are capable of laser hard welding etc. with high speed and precision.

Due to their high power, these lasers are used in various industries, like steel, metal industries, automobile manufacturing, shipbuilding, medical equipment manufacturing, and the production of electronic components, etc.

A fiber laser is a type of solid-state laser that uses an optical fiber as a gain medium. The core in the center of the fiber is doped with a rare-earth element, Yb (ytterbium), and has the highest refractive index. A 1.1 μm Laser light and Pump light propagate in this Yb-doped center core.

In fiber lasers, the laser source is silica glass mixed with a rare-earth element. In CO2 lasers, the laser source is a mixture of gases which includes carbon dioxide. Due to the state of their source, fiber lasers are considered solid-state lasers, and CO2 lasers are considered gas-state lasers.
