What is a Fiber Laser?

Explanation of Fiber Laser Technology

Fiber lasers are common metal marking machines that use optical fiber as part of the optical path, reducing distortion and loss of the beam during transmission, which allows them to achieve high precision in cutting and marking applications.

Key Features and Benefits

• High Efficiency and Precision:Fiber lasers offer a high beam quality and are known for their ability to produce extremely precise and clean cuts. They are highly efficient, converting a significant portion of the electrical input into usable laser light.
• Long Lifespan and Low Maintenance:Due to their solid-state design and lack of moving parts, fiber lasers have a long operational life and require minimal maintenance. This makes them a reliable choice for continuous and high-volume operations.

Common Applications

• Metal Engraving:Fiber lasers are ideal for engraving on various metals, including stainless steel, aluminum, brass, and copper. They can produce intricate designs with high accuracy.
• Marking and Cutting Various Materials:Beyond metals, fiber lasers can also mark and cut a range of materials such as plastics, ceramics, and certain composites. This versatility makes them suitable for a wide array of industrial applications, including electronics, automotive, and medical devices.

What is a Mopa Fiber Laser?

MOPA fiber laser machine is a kind of colour laser marking machine that combines a master oscillator and a power amplifier. This configuration allows for independent adjustment of pulse duration and frequency, allowing for greater control of the laser output. The MOPA setup can adjust the width of the laser pulse, and this control capability enables MOPA lasers to create multiple colors on metals, enabling color marking.

Key Features and Benefits

• Adjustable Pulse Durations:The ability to adjust pulse durations is one of the main advantages of MOPA lasers. This feature enables precise control over the heat input during the marking process, reducing the risk of damage to sensitive materials.
• Versatility in Marking Different Materials:MOPA lasers can handle a wide range of materials, from metals to plastics and beyond. They are especially useful for applications that require high-contrast markings, such as serial numbers, barcodes, and logos.

Common Applications

• Color Marking on Metals:One of the standout capabilities of MOPA lasers is their ability to perform colour laser marking on metals. By adjusting the pulse parameters, MOPA lasers can create different colors on the surface of metals like stainless steel, providing a unique and visually appealing finish. So it is also called colour laser marking machine.
• Fine Engraving on Sensitive Materials:MOPA lasers are excellent for fine and detailed engraving on sensitive materials, such as certain plastics and thin metals. Their adjustable pulse durations allow for precise control, ensuring high-quality results without causing damage to the material.
