{tab Introduction}

A MOPA laser source is a great way to expand your marking capabilities and improve the quality of your marking results on certain plastics and metals. With a conventional fiber laser marker, markings on certain metals and plastics (especially if they are dark in color) can be less homogeneous and rich in contrast. The MOPA laser source is a great solution in these cases because it allows you to select pulse durations, which translates into a wider range of laser marking parameters and more marking options. As a result, the MOPA can laser mark plastics with higher-contrast and more legible results, mark (anodized) aluminum in black, and create reproducible colors on steel.

Selectable pulse durations not only improve laser marking results on certain metals and plastics, but also provide more marking capabilities. With the MOPA laser, the pulse durations can be set to predefined values between 4 and 200 ns. Because it offers such a wide range of pulse durations, the MOPA is one of the most flexible lasers on the market. It can simulate the properties of conventional fiber laser markers (relatively long pulses) and those of classical solid state lasers (relatively short pulses) such as Nd:YAG or Nd:YVO4 (vanadate). You can also produce qualitatively equivalent markings with the MOPA laser partially faster than with the conventional fiber laser marker.

Using short pulses and lower pulse energy heat the material less, and the area of the heat affected zone is reduced. This results in more advantages and possibilities for laser marking metals and plastics:

  • Less burning/melting in the edge area of metal engravings
  • Less heat development during annealing markings on metal, which leads to a better corrosion behavior
  • Creation of reproducible annealing colors on stainless steel
  • Black marking of anodized aluminumControlled melting of plastics
  • Less foaming with plastics
  • More homogeneous and sometimes higher-contrast markings on some plastics
  • The advantages of the conventional fiber laser sources remain unchanged:

{tab A Look at MOPA Technology}

The term MOPA is actually an acronym for Master Oscillator Power Amplifier. This type of technology was a breakthrough in DUV light source design.

In traditional, single-chamber light sources, there is a trade-off between bandwidth and power, forcing you to choose between compromising performance or cost effectiveness. But with MOPA technology, you no longer have to compromise.

The MOPA design has two gas discharge chambers: the master oscillator and the power amplifier. The master oscillator generates light with a low amount of energy in a tight spectrum.

From this point, the light is then passed through the second chamber, the power amplifier, which intensifies the light to reach the necessary power levels.

As with all lasers, the process of how a MOPA fiber laser begins is the same. In order to create the light, you need to get the atoms in an excited state. As they move, they create a weak light that becomes more concentrated as more energy is added. Once this beam of light is created, it is amplified in some way to produce a focal point.

In MOPA lasers, an optical amplifier is used to create the focal point.

This is a configuration that consists of a master oscillator, which is a single-frequency laser used to inject lock one or several other lasers, and the optical amplifier.

The master oscillator produces a highly coherent beam, which is then amplified by the optical amplifier to increase the output power while preserving the main properties of the oscillator.

If it also contains a fiber amplifier to boost the output power, these types of laser systems may also be referred to as master oscillator fiber amplifiers (MOFA).

With the ability to modify and increase output power without changing the geometry, shape or operation principle, MOPA fiber lasers are the most popular way to achieve power scaling.

{tab Materials}

1. Aluminum
Aluminum is one of the most commonly marked substrates, and we use it in many industries. Typically, with lighter marking intensity, aluminum will turn white. anodized aluminum looks good , but white marking is not ideal for bare and cast aluminum. More intense laser settings provide a dark grey or charcoal color. Each DLM fiber laser engraving machine is capable for aluminum marking. The ideal system for your application depends on your laser marking requirements. Ablation is the most common marking technique for anodized aluminum, but some people call for etching or engraving.

2. Brass and copper
Brass and copper have high thermal conductivity and thermal transfer properties. So we use it for wiring, printed circuit boards and pressurized flow meters. Their thermal properties are ideal for laser marking systems for metal because the heat is quickly dissipated. This reduces the impact the laser can have on the structural integrity of the material. Every DLM fiber laser engraving machine is capable of marking on brass and copper and the ideal system for your application depends on your marking requirements. The best marking technique depends on the finish of the brass or copper. Smooth surfaces can offer a soft polished marking affect, but also can do annealed, etched, or engraved. Etching or engraving is best in order to provide readability by humans and machines. In some cases a dark anneal can work, but surface irregularities can cause reduced readability.

3. Tungsten and Carbide
Tungsten and Carbide are two of the hardest metals on earth and are widely used in tooling and cutting applications. Another popular segment for these substrates is wedding bands for men. Tungsten and carbide are receptive laser marking metals and laser engraving metals. Each and every DLM Laser series is capable of marking on tungsten and carbide and the ideal system for your application depends on your marking requirements. For carbide, because of the darker color it naturally has, getting a contrasting mark is rather easy with even light laser intensity. A white color is most common when polishing or annealing carbide and the contrast is extremely good.

4. Chrome
Chrome plating provides a stylish and sophisticated finish, and usually requires minimal laser intensity to remove or get through the plating. we need take ensure the marking happens on the surface only, with no impact to the chrome plating. Each and every DLM Laser series is capable of marking on chrome plating and the ideal system for your application depends on your marking requirements. We have found that lower powered, faster pulsing lasers yield the best results. Anneal or polish to protect the plating. The annealed marking is black and the polished marking is white.

5. Coated and Painted Metal

Usually we protect metals from corrosive elements through many different coating. Some coatings are thicker and require more intense laser settings to completely remove, such as powder coat. Other coatings are thin and can only protect only the surface, such as black oxide. These are much easier to ablate and will provide great contrast marking.

Each and every DLM Laser series is capable of marking on coated and painted metals and the ideal system for your application depends on your marking requirements. Our more powerful fiber lasers come in 20-50 watts, and can easily remove the powder coat and mark the underlying surface. Our fiber lasers can ablate, etch and engrave coated metals.

6. Carbon fiber
Carbon fiber is easy to mark, as the laser typically does not threaten the integrity of the material. However the composition and color of the carbon, so the resulting laser mark is always black, which limits contrast and readabil
