“Power” for the crystal 3D laser machine

 

 

“What is the power for this machine?” “What can I get if we use more power?”

This is a post talking about the “power” for the machine, mainly to help you understand the power, the engraving quality, and the engraving speed.

 

Experienced users of fiber laser marking machines understand that higher power results in improved speed and performance. However, is this theory also right for the crystal 3D laser machine? To get the answer, you need to first know how the green laser works on the crystal.

 

Don’t like fiber laser marking machines and engraving machines, green lasers don’t remove anything from the crystal. The green laser makes very very small crack on the crystal, usually 20-40um. These cracks will be like the small white dots, and the large of small dots make the image. To make the right crack, we need very precise control over the energy of the machine. Too much output power will just explode the crystal.

 

 

 

So, for the crystal inner engraving machine, higher power can’t bring you higher engraving speed and better performance; it will just explode the crystal.

Usually, the machine will mark a maximum machine power, like 3W. However, you can only use a fixed power to do the crystal inner engraving, like 1.2W. You need to set this output power in the machine software.

You can’t use 1.0W, as this can’t make the crystal crack. You can’t use 1.3W, that will make the crystal explode. So the machine's max power is meaningless for use.

 

The only chance you need to raise the machine power you use is when the laser source has a problem. The laser source box is a semiconductor laser, the laser source has a useful life. When the machine uses a very long time, like 10 years, the laser will attenuate. This time, you raise the power setting in the machine to compensate for energy loss.

For the machine power, there are also many different meanings. The machine output power, the machine max output power, the machine module power, the laser source output power, and the laser source max output power. Many different “power”s. Please kindly figure out what the “power” is on the data sheet.

All I mentioned above is the machine's (max) output power under the lens, which works on the crystal.

 

Then there must be some question, if the higher power can’t bring better engraving quality, then how can we increase the engraving quality? That is something to do with the laser box level and quality, and the crack shapes. Different levels of laser source boxes will produce different shapes of cracks.
