The working principle of Ming Yu Laser fiber laser machine

Release time:2024-08-22

Mingyu Laser fiber laser machine, with its unique fiber laser technology as the core, is widely used in high precision machining fields such as metal engraving and plastic engraving. The key to this device is that it uses glass fiber doped with rare earth elements as the gain medium, thus achieving efficient laser output on the basis of fiber amplifiers.

In the optical fiber laser machine, the optical fiber is the core component, and its manufacturing is based on SiO2 matrix materials, which are carefully drawn to form glass solid fibers. The light guiding principle of optical fiber depends on the principle of total reflection of light, that is, when the light is incident from the high-refractive index medium (optically dense medium) to the low-refractive index medium (optically sparse medium) at an Angle greater than the critical Angle, the light will be fully reflected and all return to the high-refractive index medium, ensuring the efficient transmission of optical signals in the optical fiber.

The structure of a common bare fiber consists of a high-index glass core in the center, a low-index silicon glass cladding in the middle and a reinforced resin coating in the outermost part. Together, these components ensure the stability and durability of the fiber. According to the different modes of propagation of light waves, optical fibers can be divided into single-mode fiber and multi-mode fiber. Single-mode fiber has a small core diameter, can stably transmit a single mode of light, and small inter-mode dispersion, which is suitable for long-distance transmission and high-speed data transmission. The multi-mode fiber has a larger core diameter and can transmit multiple modes of light at the same time, but the dispersion between modes is larger, and it is more suitable for short-distance transmission and low-cost applications.

Taking Mingyu Laser's rare earth doped fiber laser as an example, its working principle is more advanced. In the device, an optical fiber core doped with rare earth ions acts as a gain medium and is carefully fixed between two mirrors to form a resonator. When the pump light is incident on the fiber from the M1 end, the rare earth ions in the fiber will quickly absorb the energy of the pump light, and its electrons will be excited to a high energy state, and the particle number will be reversed. Subsequently, these excited particles, in the process of returning to the ground state, will release laser light in the form of radiation and output through the M2 terminal.

With its unique working principle and efficient and stable performance, Mingyu laser fiber laser machine has shown excellent application value in the fields of metal engraving and plastic engraving. Its high-precision and high-efficiency laser output has injected new vitality into the development of manufacturing.
