• 

GOLDEN LASER(stock number 300220) is a china pipe cutting machinemanufacturer which focuses on the application and practice of the laser industry. After more than 15 years of hard work, we have become the golden laser machinebrand with the highest market share of laser applications, the most vital international influence in the laser industry.

Fiber laser machine is widely used in daily life. So, how does fiber laser machine work?

Ⅰ. Profile of fiber laser machine

Fiber laser machine is a mid-infrared laser with great development potential with optical fiber as the working material. According to its emission mechanism, it can be divided into rare-earth doped fiber laser machine, fiber nonlinear effect laser, single frequency fiber laser machine, fiber soliton laser, etc. Among them, the rare-earth-doped fiber laser machine has been very mature, such as erbium-doped fiber amplifiers have been widely used in optical fiber communication systems. High-power fiber laser machine is mainly used in military, laser processing, laser medical and other fields.

Ⅲ. How does fiber laser work?

Taking rare-earth-doped fiber lasers as an example, a fiber core doped with rare-earth ions is used as a gain medium, and the doped fiber is fixed on two mirrors to form a resonant cavity. When the semiconductor pump laser passes through the optical fiber, the rare earth ions in the optical fiber absorb the pump light, and their electrons are excited to a higher laser energy level, realizing the particle inversion. The inverted particles transfer from a high energy level to a ground state in the form of radiation, and output laser light.
