The temperature control system is necessary for the laser machine

 

We all know that light can raise the temperature of the object. But do you also know that “the temperature can affect the light”?

Since light does not require a medium to propagate, strictly speaking, temperature does not affect the propagation of light in nature.

However, for the processing application with laser, the light needs to be strengthened and output at a certain frequency before it can be used. The generation and enhancement of lasers are made by electronic components.

When electrical energy is converted into light energy, a large amount of heat is also converted. The heat causes the temperature of electronic components to rise, thus affecting the performance and stability of light.

Therefore, the saying that "temperature affects light" is mainly about temperature affecting electronic components, and electronic components affecting light. "

Similarly, if the laser generator is placed at a lower ambient temperature, the light will also be affected.

 

After knowing how the temperature affects the laser, then we will realize that the temperature control system is very important.

For the temperature control system, it includes the temperature detection system and temperature control system. As the laser source is just a part of the laser source and is sensitive to the temperature, we need to put one temperature detection to the laser source and put the temperature control to it.

Finally, we also need the cooling system for the whole machine, it usually will be fans or a water cooling box.

 

In the market, we often see that some laser light source boxes are relatively large, while others are relatively small. This is because some laser light source boxes contain temperature control systems, while others have temperature control systems outside the laser light source boxes. Of course, there are also some laser manufacturers with strong technical strength who can make the laser light source boxes very small even if they put the temperature control system inside the laser light source box. Usually, these small laser source boxes have special material requirements for laser components.
