In the process of using fiber laser marking machine, if the laser intensity is not enough, it will affect the clarity of the marking. Perfect laser share laser marking machine strength is not enough solution, you can come to pay attention to. 

First of all, in order to solve the problem of insufficient laser intensity of fiber laser marking machine, we must find the cause of such failures. If the intensity is not enough due to the aging of the laser resonator, you can fine-tune the resonator lens to make the output light spot better; If it is because of the deviation of the acousto-optic crystal or the low output energy of the acousto-optic power supply, it is necessary to adjust the position of the acousto-optic crystal of the laser marking machine or increase the working current of the acousto-optic power supply to make the mark more clear. 

Above is the laser marking laser intensity is not enough solutions, I hope you can adopt.
