The difference between MOPA laser marking machine and general laser marking machine:
Generally, laser marking machines are a bit depth of aluminum materials, nothing special. The laser marking effect is good or bad to the laser marking machine. The conventional optical fiber is ordinary marking. The pulse width can adjust the narrow vein wide high -frequency high -frequency optical fiber Mopa laser marking machine or end pump, which can be blackened, just like the identification of iPad.
The pulse wide -adjustable optical fiber laser marking machine has a wider and more practical range than ordinary fiber laser marking machines. Of course, the price will be more expensive. You can choose according to your products and processing requirements.
Compared with the general laser marking machine, the prominent feature of the MOPA marking machine is that the pulse is wide and the frequency range is large. Generally, the laser marker veins are width, with a range of about 80-120NS and the frequency of 20kHz-80kHz.
The MOPA marking machine (take the 20 watts of YLPM of IPG as an example) pulse width of 2-200ns can be adjusted, and the frequency is 1.6kHz-1000KHz.
MOPA has a wide range of marked veins and a wide range of frequency. Therefore, there are many parameter combinations, and there are many effects that can be done, and there are many suitable materials products.
MOPA laser marking machine can also be used to play color, and general laser marking machines cannot be done. When laser label stainless steel materials, it can change the color change of the surface layer of the material by adjusting the laser beam to obtain different decorative effects of color. Its advantage is that its pulse width and frequency are independent and adjustable. Adjusting one of them does not affect other laser parameters. This characteristic has unlimited possibilities for stainless steel colors.
