What are the differences between MOPA laser marking machines and ordinary fiber laser marking machines?

In modern industrial production, laser marking technology has become an important means for many enterprises to improve the quality of product marking and production efficiency due to its advantages such as high precision, high speed, and non-contact. Among the many types of laser marking machines, MOPA laser marking machines and ordinary fiber laser marking machines are two common types. Understanding the differences between them is crucial for choosing equipment that suits one's own production needs.

First, let's understand the working principles of these two types of laser marking machines. Ordinary fiber laser marking machines directly output laser through fiber lasers, and their laser wavelengths are relatively fixed. However, MOPA laser marking machines adopt the structure of a master oscillator and power amplifier, enabling more flexible adjustment of laser pulse width and frequency.

In terms of performance characteristics, due to the adjustability of pulse width and frequency, MOPA laser marking machines can achieve finer and more complex marking effects, such as creating color marks on stainless steel. In contrast, the marking effect of ordinary fiber laser marking machines is relatively simple.

For example, in the electronics industry, ordinary fiber laser marking machines are often used for simple marking on mobile phone shells; while MOPA laser marking machines can be used for marking tiny circuits on chips. In the jewelry industry, ordinary fiber laser marking machines are generally used for marking the basic styles of metal jewelry, and MOPA laser marking machines can achieve complex pattern and texture engraving.

According to relevant research reports, as the requirements for product marking in the manufacturing industry continue to increase, the market share of MOPA laser marking machines is gradually expanding. In the future, MOPA laser marking machines are expected to be widely used in more high-end manufacturing fields, while ordinary fiber laser marking machines will continue to exert their cost advantages in some basic application scenarios.

In conclusion, there are obvious differences between MOPA laser marking machines and ordinary fiber laser marking machines in terms of working principle, performance characteristics, application scenarios, cost, and maintenance difficulty. When choosing, enterprises should comprehensively consider various factors based on their own production needs and budgets and select the most suitable laser marking equipment for themselves. I hope that through the introduction of this article, it can help you understand the differences between these two types of laser marking machines more clearly and provide useful references for your production decisions.
