We all know that fiber laser diodes are widely used in daily life, but many people still don't know what role they play and where they are mainly used. Today, Xiaobian will give you a brief introduction.

Fiber laser diode, in short, is a core light source used to "excite" or "pump" fiber laser. It doesn't diverge like an ordinary LED, but emits very concentrated and directional light.

Fiber laser wants high power output, which is inseparable from this small "laser heart". It injects energy into the gain medium through optical fiber, so that the whole equipment can continuously output strong light, and it can also ensure stable wavelength and high beam quality. This kind of stability is incomparable to many other light sources.

So where is it mainly used? In fact, the scope is particularly wide.

Industrial processing is the biggest part, such as laser cutting, welding, marking and drilling, which are almost inseparable from fiber lasers, and fiber laser diodes are working silently behind fiber lasers.

It is also indispensable in the medical field, such as laser surgery, skin beauty and ophthalmology treatment. These devices need very precise and controllable light sources, and the high brightness and high stable output provided by fiber laser diodes are particularly suitable.

The current trend is also quite obvious. Everyone is pursuing laser diodes with higher power, higher efficiency and longer life. It used to decay in a few hundred hours, but now it can run for tens of thousands of hours.

When we do experiments ourselves, we often debug the heat dissipation structure and packaging method repeatedly, because even the best chip can't stand it as long as the temperature is not controlled well. This business, looking at the world of light, is actually behind the wrestling of temperature, current and materials science.

The above is the function and main application direction of fiber laser diode. If you still don't understand, please feel free to contact us.
