➡️MOPA stands for Master Oscillator Power Amplifier. The laser type consists of two main components:
• Master oscillator (produces the beam, MO)
• Power Amplifier (optical amplifier, increases the output power, PA)
💡The light from marking lasers is emitted in pulses and this pulse duration is fixed. With the MOPA laser, however, the pulse duration can be set variably. Depending on the application, long or short pulses of 1-500 ns can be realized.
➡️Even more flexibility is achieved through the independent adjustment of the laser parameters - pulse duration, pulse frequency and pulse energy. The laser can therefore be adapted very precisely to the material.
In our example image, a dark marking was created on natural anodized aluminium without damaging the anodized layer - it was "only" recolored.
➡️ This maintains full corrosion resistance and makes MOPA marking ideal for areas of application where resistant markings are required. Other examples include the marking of medical products, as the marking must be extremely due to the countless sterilization processes.
