Color laser marking

In some cases, the use of laser engraving to obtain conventional colors such as black, white and gray may be limited. 
The best and most popular method for performing color engraving or color marking is to use MOPA fiber laser. 
How to carry out color laser engraving?
Although any fiber laser can be used for engraving metals, it is recommended to use MOPA fiber laser for color engraving. 
Compared with conventional fiber lasers, MOPA fiber lasers can better control parameters such as power, frequency and pulse width. 
As for the color marking, the appropriate metal is stainless steel. It cannot be used to mark different colors on other materials. 
The JPT M7 series high-power MOPA (Master Oscillator Power Amplifier) fiber lasers adopt the MOPA configuration of the master oscillator and power amplifier, demonstrating outstanding laser performance and high-level controllability of time pulse shaping. 
Compared with Q-switching technology, in the MOPA configuration, the pulse repetition frequency (PRF) and pulse width can be controlled independently. By adjusting different combination parameters, the laser peak power can be well maintained. High output power has its advantages, especially in high-speed marking applications. 
JPT MOPA fiber laser is the most suitable for marking and marking processes, such as black marking on anodized aluminum, color marking and deep engraving on stainless steel.
