Advantages of the MOPA Nanosecond Pulse Laser Source Series

1. The pulsed fiber laser sources in the GL series are compatible with the MOPA scheme.

2. The MOPA fiber laser source series has a wider frequency range, higher control precision, and superior first pluse when compared to the Q-switched laser source.

3.Powerful and economical 500W pulse laser cleaner With a 500W MOPA laser source and multiple beam mode, you can complete all laser cleaning tasks with optimal efficiency, including rust, oil, oxydation, and paint removal, among other tasks. This laser cleaner is suitable for almost all manual cleaning tasks.

How does a MOPA Laser Source work?

Conventionally, nanosecond pulsed fiber lasers based on electrically modulated seed sources and multi-stage power amplifiers are referred to as MOPA laser sources in the industry. It is mostly used for laser marking and precision cutting, but it can also be used for welding, drilling, and other tasks. SPI is a sexual manufacturer, and JPT and Guangzhi Technology are domestic representative manufacturers.

In comparison to the single oscillator configuration, the mopa laser source is a laser. In English, it is referred to as a Main Oscillator and Power Amplifier. It is not a particular kind of laser source.

The Fundamentals of the MOPA Laser Source

The MOPA laser source: To achieve high-power amplification of the seed source and obtain the required high-energy pulsed laser light, the pump light and the seed signal light are coupled into the double-clad fiber for amplification.

What benefits does a mopa laser engraving machine provide?

• Risk to metals When using a laser to engrave metals, the heat applied to the surface of the metal and subsequent burning or melting of the edge area can cause these materials to react with their surroundings and form rust. Because MOPA lasers produce less heat, they cause less damage to the metal and increase the product’s resistance to corrosion.

• The process of color marking stainless steel by annealing does not remove any material during processing. The application of heat results in the formation of colors when laser marking stainless steel using the annealing method. A MOPA laser source’s ability to precisely mark colors and reproduce them is a more recent benefit, although the possibility of creating colors with a laser machine has been around for some time.

• Anodized aluminum with a black mark

The top layer of anodized aluminum is typically removed with a laser to reveal a white mark. On colored anodized surfaces, this kind of mark is particularly obvious; however, a white mark is not as obvious on natural aluminum that has been silver anodized. You can set very short pulse durations with a MOPA laser source, so the anodized layer is not removed but simply repainted. Although the process of black marking is distinct from that of reproducing colors on stainless steel, the end result is comparable.

• Greater precision when melting plastics

The adaptability of a MOPA laser’s pulse duration also makes it very useful for making marks with a high contrast on plastics. Marking plastic with a fiber laser typically results in foaming and melting, which compromises the mark’s quality. There is less foaming and unintentional melting when less heat is applied, resulting in a more uniform mark.

A MOPA source laser also has the advantage of having a longer lifespan and requiring less upkeep than a regular fiber laser. A laser engraving machine with a MOPA source is definitely something to think about if you want to mark a variety of surfaces and color metals.

Applications of MOPA Laser Technology

Color-engraving metals, particularly stainless steel and black marking anodized aluminum, is the primary use of a MOPA laser. It can engrave 16 or more colors on stainless steel.

As the laser beam causes a chemical reaction on the stainless steel, it engraves each color separately, leaving a superficial permanent mark.

When marking surfaces made of plastic that don’t require a lot of melt burns, MOPA lasers can be used. Also, the engravings made with a MOPA laser on dark plastic are easy to see.

It might be an alternative to the pricey UV lasers that are used to engrave plastic.

However, MOPA cannot be considered a less expensive alternative because it is more expensive than the majority of other fiber laser engravers that are capable of excellent plastic engraving.

If your application requires color-engraving metals and black marking anodized aluminum, you only need a MOPA laser engraver.

For most other types of engraving, a standard fiber laser is sufficient.
