Laser, as the name suggests, is a device that can emit laser. It is classified according to the working medium. It mainly includes four categories: solid laser, gas laser, semiconductor laser and dye laser.The fiber laser is a type of solid laser. It is characterized by using glass fiber -mixed with rare earth element as a gain medium.
Optical fiber laser principle
The principle of optical fiber laser is the pump light emitted by the pump source into the gain medium through a reflector coupling. Since the gain medium is a rare earth element optical fiber, the pump light is absorbed, and the rare earth ion that absorbs the photon energy can occur.Leaping and realizing particle number reversal. The particles after reversal pass through the resonance cavity, which will be transmitted back to the base state by the excitation state, releases energy, and forms a stable laser output.
Fiber laser structure
The composition of the fiber laser is not much different from the traditional laser (solid, gas, and liquid laser). It is also divided into three basic elements: pump source, gain medium, and resonant cavity.Among them, most of the pump source is a laser made of semiconductor materials. It has high power and allows optical fiber laser technology to occupy great advantages in high -speed and large -capacity modern communications.The gain medium is essentially a fiber, so it can form a particle number reversal after absorbing the optical particles, or generate radiation through non -linear gain.After amplified radiation, it can be used as a stable output signal of the device.
Fiber laser application
The application of the fiber laser in the scale: The pulse fiber laser has a good beam quality, and its reliability allows us to achieve a long time of maintenance.In addition, we will also find that the electric light conversion efficiency is very high.Its pulse duplicate frequency and minimum volume, as well as the simplest and most flexible use of water cooling, coupled with cheap operating fees, all the above advantages make it the only choice for high -speed and high -precision laser marking.

Fiber laser advantages
1. The cost of low cost and continues to decline The gain medium of fiber laser is glass fiber, while the manufacturing cost of glass fiber is very low, and the technology of glass fiber is very mature.In addition to the gain medium, the main component of another fiber laser cost is its pump. With the development of optical communication technology and the rapid expansion of the market capacity, the semiconductor pump of optical laser shows a downward trend.Therefore, low cost is one of the significant advantages of fiber laser.2. One of the main limit factors of the power laser that can have higher power laser is the heat dissipation performance, because optical fiber lasers use optical fiber as a gain medium, which makes it a larger surface area at the same volume, which also makes the light road heat dissipation performance very very goodExcellent, which also means tolerable laser power is higher.When other types of laser are considering increasing the laser power, they also spend their efforts on the heat dissipation of the gain media, which is characterized by the optical fiber laser.
