The appearance of the mopa machine produced by Foshan Fulan Laser is the same as that of the ordinary optical fiber machine. The wavelength of mopa machine and ordinary fiber laser marking machine is 1064 nm. So, how can we distinguish between mopa and ordinary optical fiber?

Next, please follow Foshan Fulan Laser Technology Co., Ltd. to understand the difference between mopa and ordinary fiber laser marking machine.

1. Blackening of aluminum oxide and aluminum alloy:

MOPA marking machine can black the surface of aluminum (aluminum oxide, aluminum alloy, etc.) in a shallow layer, smooth and pure black. Ordinary optical fiber machines cannot produce smooth and pure black effect.

2. Marking fineness:

Both Mopa and ordinary optical fiber laser marking machines are suitable for marking metal and non-metallic materials, but the marking effect of mopa laser marking machine is relatively fine, and the effect of ordinary optical fiber marking machine will be rough and not so fine.

3. Pulse width and frequency of laser equipment:

The pulse width of MOPA marking machine is adjustable and the frequency range is wide. The pulse width of ordinary optical fiber machine is fixed.

4. Metal deep carving:

The Mopa machine can't drill too deep on the metal material, even can't drill the depth; Ordinary optical fiber can mark depth on metal materials, but there are certain requirements for laser power. At least optical fiber machines with 30W and above are required. The more times the same place is repeatedly marked, the deeper the mark will be.

Of course, it is generally not necessary for users to distinguish whether it is a mopa laser marking machine or a fiber laser marking machine, because the equipment delivered by Foshan Fulan Laser will have a nameplate identification, and the relevant parameters will be marked on the nameplate. Just look at the parameters on the nameplate to know what type of equipment it is.
