Overview of nanosecond fiber laser applications
Laser cutting is one of the most popular material processing applications for fiber lasers, excluding marking. While cutting is typically performed with high-power CO₂ or fiber lasers, marking is primarily done using nanosecond fiber lasers.
Nanosecond fiber lasers are used in micromachining processes such as drilling, engraving, and cutting due to their control and versatility. Although they deliver only a few millijoules of pulse energy, they provide high peak power and excellent beam quality, making them ideal for various niche applications.
Advantages in high-speed processing
Nanosecond fiber lasers are often used with scanner-based beam delivery systems that enhance processing speed. When power density is insufficient, surface marking can shift toward deeper engraving, suitable only for materials of certain thickness. These lasers also have specific applications in battery manufacturing.
Replacing traditional processes
Nanosecond fiber lasers may replace traditional slitting and stamping processes thanks to their flexibility and control. Single-mode lasers are effective for cutting bare metal foils, offering high speed and excellent edge quality. However, they are not suitable for cutting coated electrodes.
Applications in the solar industry
Nanosecond fiber lasers are widely used for scribing in the solar industry. They help reduce resistive losses and improve overall performance, offering high-quality results with minimal thermal damage.
Applications in the jewelry and metal industries
Nanosecond fiber lasers are widely used in the jewelry industry. Their high peak power allows effective processing of metals such as silver and gold. They are ideal for marking, cutting, and engraving, giving manufacturers greater flexibility. Another application is wire cutting, suitable for both soft and hard metals.
Applications in other materials and industries
Nanosecond fiber lasers are used not only for metals but also for other materials. They are effective for cutting and marking complex components in industries such as medical device manufacturing. Suitable materials include silicon, ceramics, plastics, and polymers.
In conclusion, nanosecond fiber lasers have proven to be cost-effective solutions for cutting both hard and soft materials. Engineers and manufacturers should consider them for innovative manufacturing applications.
