Non-smart fiber laser 30w

The laser source is the most important part of a fiber laser machine. There are different models of Rekas fiber laser sources with very different prices and qualities. The best laser source models are the Rekas Q, QB, and MAX sources, which are more than 40 million more expensive than the weaker model (Rekas QS). So if you see a Rekas fiber laser at a very low price, it is a Rekas QS laser. See the following article to identify the laser source model.
