The difference between fiber laser of MOPA laser marking machine
Many clients ask us about the difference between fiber laser and MOPA laser marker,so we will talk about it.
What is MOPA laser marking machine?
If The most popular way of achieving power scalability is the “MOPA” (Master Oscillator Power Amplifier) approach. The “MO” produces a highly coherent beam, and an optical “A” is used to increase the power of the beam while preserving its main properties. The “MO” has no need to be powerful, and has no need to operate at high efficiency because the efficiency is determined mainly by the “PA”. The combination of several laser amplifiers seeded by a common “MO” is essential concept of the High Power Laser Energy Research Facility. This is mopa fiber laser marking machine.
Mopa is also belong to a kind of fiber laser, so firstly, let me start with pulsed fiber laser, pulsed fiber laser types mainly include two types of Q-switching technology and MOPA technology.
The machine use Mopa technology, mostly use for marking color on Stainless steel, black and gray color on aluminium oxide, for example, iphone ipad, all kinds of plastic. MOPA Laser with big laser power also use for deep marking on metal product. In addition, Mopa adopt quality 20W 30W JPT M1 M6 M7 laser source and Galvo scanner head. Recently more and more customer use MOPA colour laser engraving machine for personalise and rework the backcase of watch. So you can see the different about fiber laser color marking and mopa laser marking machine as below
Application:
1. If color marking on stainless steel,with mopa fiber laser marking machine, we can do many beautiful color on stainless steel, such as red, blue, pink, green etc.
3. fiber laser marking machine can only do ordinary marking on anodised aluminium.But MOPA laser marking machine we can do black marking on anodised aluminium easily.
4.Phone case,mopa laser marking macine can mark on IPone covers.
5. White marking on black plastic & black marking on white plastic.
6.For mopa,it will help you do other work ,if you need to mark on color on stainless steel,you can choose it.
The difference bwtween MOPA laser marking machine with fiber laser marking machine:
1.Applications:
When we buy a new machine, we want to use it to meet our demands and improve work efficiency.
Fiber laser can mark and engrave on all metal materials and part of the plastic.While MOPA laser is one of fiber laser.
Firstly,It is able to do the basic work of fiber laser.
Secondly,it also can mark colors on stainless steel(yes, only on SS) and black colors on anodised aluminum.
By the way,it can only mark on the metal surface when it do these two jobs.
That’s why we recommend our clients choose 20w or 30w when they need to mark colors.
2.Laser power:
If you want to mark colors on stainless steel, 20w or 30w is ok.The spead of 30w is a litter faster than 20w. It has no 50w.
Fiber laser common power is 20w,30w and 50w.20w is mainly used for surface marking, 30w can do a little engraving(≤0.5mm）,and 50w is suitable for deep engraving.
Mopa is mainly used for stainless steel coloring and anodized aluminum blacking.
Because it can make the laser stay on the material shorter.And it has enough energy to clear the anode layer.
Mopa laser is the best choice for the processing of thin aluminum oxide surface peeling anode.
Because the Mopa laser can flexibly adjust the pulse width and frequency parameters, not only can the line drawn be finer, but also the edges appear smoother.
With the smaller vessel parameters of Mopa laser, the material is not easily deformed.And the shading is more delicate and bright.
Mopa lasers have a wide pulse width and pulse frequency adjustment range. Using the parameters of narrow pulse width and high frequency can make a black effect on the surface of the material. Different gray scale effects can also be marked through different parameter combinations.
Main Functions Of 3D Fiber Laser Marking Machine
Laser marking machine have very fast development nowadays, we can see 2D laser marking machine have very wide application in so many fields. But the disadvantage of 2D laser is it can only work on the flat surface. With the help of rotary device, we can use it mark some cylinder, such as cup. Even in this case, it have many limitation on curved surface marking. So 3D fiber laser engraving machine rise in the market.
3D means Dynamic focusing, compare with ordinary 2D laser machine, 3D laser marking machine use different galvo head. Ordinary 2D scanning head only have two mirrors, but 3D scanning head have three mirrors. The third mirrors can move forward and backward. This is the key technology of 3D laser marking machine.
Except scanning head, control card and control software is the brain of laser markers. One good control software will make complex operation become very easy. Most company will development the software together with scanning head.
How to find fiber laser marking machine focus?
When laser marking machine used, it will involve the problem of correcting the focal plane. Equipment manufacturers emphasize the importance of focal length during equipment installation training and sample adjustment. Laser laser engraving on the correct focal length surface is a key factor for the equipment to properly perform its performance. The direct users of the equipment should know how to properly debug the laser marking equipment. The focal length confused and misunderstood. Today I will give you a summary of some conventional laser marking machine focal length debugging methods.
The first method: continuous light test
Draw a square or circle of about one centimeter on the marking software, and fill it conventionally. Adjust the laser energy to a relatively large value in the laser setting parameter column, use the low frequency as much as possible, and then select continuous marking, and laser project on the product surface. Place a block such as a metal business card at the position, continuously mark the light, and shake the Y axis up and down until the laser is applied to the metal business card with the strongest energy, the clearest sound, and the brightest color, which is basically the focal length. Test a few more times to find the right focal length.
After finding the focal length, we can use a ruler to measure the distance from the down lens to the surface of the object. Use this distance as a fixed value. The next time you mark the same item, you only need to take out the ruler, so that the height of the galvanometer to the surface of the item can reach this value again.
The second method: red light point value method
It can be positioned by configuring additional red light. This method requires the device to have this hardware configuration. Install one or two oblique red lights next to the galvanometer or galvanometer. Using some principles of a right-angled triangle, use a fixed right-angled edge and two overlapping hypotenuses. Find the other right-angled side of the focal length. You only need to shake up and down until the two red light points coincide to quickly find the focal length. Although this method is convenient and fast, it requires equipment to have this device.
How to improve working efficiency of fiber laser marking machine?
Firstly,Marking density.
In the same case of format ,spot, and depth, the higher the density of the marking, the slower the corresponding marking speed. Because the density directly increases the marking area.
The primary factors affecting the fiber laser merking machine is divided into internal factors and processing of the two elements of the workpiece.
The main internal elements are laser frequency, laser spot form and beam divergence Angle, laser power, reasonable optical integration.
The first internal factors in the early model selection of time attention, should follow the laser engineer’s opinion to choose.
Another factor is the primary need for customers to pay attention to the needs of processing.
The primary marking density, marking format, marking depth and laser spot size.
Secondly, Marking format.
Since the deflection area of the large-format marking galvanometer is increased, the marking speed of the large-format surface is slower than that of the small-format marking.
It is optical fiber laser marker marking density.
In the case of the same format, equal spot and the same depth, the higher the marking density is, the slower the corresponding marking speed will be.
The original density directly increases the marking area.
Thirdly, Marking depth.
According to the demand, if the depth of the marking needs to be deepened, the parameters of the metal laser marking machine need to be adjusted. Increase the power, current and other factors of the metal laser marking machine. Therefore, these will effect marking speed.
And fiber Laser marking machines divided according to lasers. So we need to select different laser marking machines according to the working conditions, marking materials and format. As the most advanced laser marking equipment in the world, the fiber laser marking machine has a wide application range and recognized as a new generation of solid laser replacement. It has good beam quality, fast marking speed, small size and convenient use. And the working life long, and it has favored in the marking industry. To achieve the normal use of fiber laser marking machine and long life, daily cleaning, maintenance and maintenance is essential.
Because the deflection area of large format marking galvanometer increases, the marking speed of large format is slower than that of small format.
At last,Optical fiber laser marking machine marking depth.
According to the requirements, if the marking depth needs deepen,we need adjust the parameters of the fiber laser engraving machine.
So as to increase the power, current and other factors of the fiber laser marking machine.
Therefore, the above factors will affect the marking speed in these processes.
