Laser, as the name suggests, is a device that emits laser light, classified by the working medium, there are mainly solid state lasers.Gas lasers.Semiconductor lasers and dye lasers are the four main categories.The fiber laser is a kind of solid-state laser, which is characterized by the use of rare earth element-doped glass fiber as the gain medium.

Fiber laser principle

Fiber laser principle, the pump light from the pump source through a reflector coupled into the gain medium, because the gain medium is rare earth element doped fiber, so the pump light is absorbed, absorbed photon energy rare earth ion energy level jump and achieve particle number inversion, after the inversion of the particle through the resonant cavity, from the excited state jump back to the ground state, release energy, and form a stable laser output.

Fiber laser structure

.
The components of a fiber laser are the same as those of a conventional laser (solid.Gas.The components of a fiber laser are not very different from those of a conventional laser (solid. gas. liquid. laser), and are also divided into a pump source.Gain medium.Resonant cavity these three basic elements.The pump source is mostly made of semiconductor material lasers, with high power, so that fiber laser technology in the high rate.High-capacity modern communication occupies a great advantage.The gain medium is essentially an optical fiber and is therefore capable of creating particle number inversion after absorbing light particles, or generating radiation through nonlinear gain.The amplified radiation is then used as a stable output signal for the device.

Fiber Laser Applications

Fiber laser applications in scale: pulsed fiber laser has a very good beam quality and its reliability allows us to achieve a very long maintenance-free time.In addition we will also find that the electro-optical conversion efficiency on the whole is very high.Its pulse repetition frequency and minimal size, as well as the simplest and most flexible way to use it without water cooling, plus the cheap running costs, all the above advantages make it the only choice for high speed and high precision laser marking.

Fiber laser advantages

1. low cost and continue to decline fiber laser gain medium for glass fiber, and the manufacturing cost of glass fiber is very low, and the technology of glass fiber has been very mature.In addition to the gain medium, another major component of fiber laser cost is its pump, with the development of optical communication technology and the rapid expansion of market capacity, the semiconductor pump of fiber laser shows a decreasing trend.Therefore, the low cost is one of the significant advantages of fiber lasers.2. Can have a higher power laser power one of the main limiting factors lies in the heat dissipation performance, because the fiber laser is using optical fiber as the gain medium, which makes it have a larger surface area in the same volume, which also makes the optical path heat dissipation performance is very good, which also means that can withstand the higher laser power.Other types of lasers, when considering increasing laser power, also spend a lot of effort on the heat dissipation of the gain medium, a feature unique to fiber lasers.
