200kW Raycus Fiber Laser

How Thick of Steel Can Be Cut by a 200kW Raycus Fiber Laser?

Unmatched Cutting Power

Compared to a 120kW fiber laser, Raycus’ 200kW laser doubles overall cutting efficiency. According to Raycus, the machine’s cutting capacity can reach a staggering 800 mm of steel. This milestone in cutting power is set to improve further as processing techniques and technologies evolve.

Such immense cutting power offers enhanced productivity, reduces production costs, and opens up new opportunities for industries that need to cut extremely thick steel materials. The machine not only handles thicker materials but also widens the range of applications where laser technology can be employed.

Technological Innovation Behind the 200kW Laser

This advancement is driven by Raycus’ innovations in ultra-high-power laser technology. The 200kW laser is built on a fully forward MOPA (Master Oscillator Power Amplifier) structure platform and incorporates the fourth generation of Yb-doped circular modified fiber. Key features include:

• High absorption and wavelength stability
• Excellent beam quality and high threshold for transverse mode instability (TMI)
• Long-term operational reliability with excellent suppression of photodarkening and coating durability against aging
• A custom fiber waveguide structure designed for high-power and high-beam quality

The third-generation ultra-high-power laser transmission system also integrates active beam control and passive nonlinear effect control, enhancing precision. Raycus’ patented technologies like a 19*1 ultra-high-power beam combiner and active divergence angle control contribute to superior beam quality (BPP ≤ 12@270, BPP ≤ 13@300), making this laser a game-changer in industrial cutting.

Applications for Ultra-Thick Materials

The primary need for a 200kW fiber laser machine arises in industries with extremely thick steel or specialized materials. For example:

• Shipbuilding: Large commercial ships, oil tankers, and military vessels require steel plates that are often 60–100 mm thick or more.
• Nuclear Power Plants: Safety requirements mandate steel plates that are up to 200 mm thick.
• Heavy Construction Equipment: Specialized machinery and structural components often use very thick materials, sometimes exceeding 100 mm.

For these industries, a machine capable of cutting steel up to 800 mm thick, like the 200kW fiber laser, could be invaluable. Traditional cutting methods, such as plasma or flame cutting, may struggle with both the precision and speed needed for such thick materials.

Cutting Efficiency and Productivity

For industries focused on productivity, the 200kW fiber laser can drastically reduce cutting times, improve cutting precision, and eliminate many post-cutting processes (such as smoothing or deburring). This can be critical in industries with high demand, where minimizing production cycles and maximizing output are key. Additionally, the ability to cut thicker materials with laser precision opens new possibilities in manufacturing, where traditional methods fall short in terms of quality and speed.

Emerging Industrial Needs

Industries are evolving, and the need for cutting-edge technologies continues to grow. As industries such as aerospace, defense, nuclear power, and heavy manufacturing push the limits of material thickness and complexity, demand for higher-powered fiber lasers is likely to increase. If a manufacturer aims to future-proof their operations or enter new markets, a 200kW fiber laser might be seen as a strategic investment.

Is a 200kW Fiber Laser Necessary?

• Yes, if:
  • You work with extremely thick materials (up to 800 mm) regularly.
  • You are in an industry where speed, efficiency, and precision for thick materials are crucial.
  • Your operations demand cutting-edge technology to remain competitive in heavy industries.
• No, if:
  • Your material thickness requirements do not exceed 50–100 mm regularly.
  • Your current cutting solutions (such as 12kW or 20kW fiber lasers) are meeting your needs.
  • The high cost of a 200kW machine would not provide a justifiable ROI in your production environment.
