Pulsed and Continuous Wave (CW) Green Fiber Lasers
Fiber laser systems for engraving are increasingly gaining popularity and are even taking the place of older laser technologies. Numerous modern industries apply direct laser marking in their operations. Fiber lasers provide a benefit for engraving due to their capacity to create a lasting imprint on various materials. Additionally, these laser systems have resistance to any form of abrasion not involving any contact.
How fiber laser engravers work
The operating principle of fiber laser engravers is based on the laser beam that is directed to the material, and the material changes color depending on the time the two are exposed, resulting in a mark. The laser beam originates from light amplification by energy emission and absorption. The resonator components include glass fibers that can be pumped by diodes to emit a laser beam with a small wavelength, for instance, 1064.
Precision and material versatility
Fiber laser engravers are popular because the engraved details are always precise; they do not create a tear. The accuracy is maintained during the whole process. The fiber laser systems for engraving have a tiny diameter but high intensity. Fiber lasers are perfect for marking such materials as plastics and hard metals.
Fiber laser engravers include a laser engine, a control software, and a scan head. Laser systems can be used not only for engraving and marking, their applications also contain material removal, material cutting, and scribing. Moreover, fiber laser systems demonstrate high efficiency when compared to conventional lasers: they provide “speed, flexibility, and reliability that is required to process certification standards, and achieve maximum quality control.”
Why fiber lasers are highly efficient
Resistance to misalignment and vibration
Compared to most lasers, fiber laser systems for engraving are not sensitive to movements. “When most lasers are knocked, their whole laser alignments are thrown off. If the optics get misaligned, getting them to function again is not easy, and it requires a specialist.” Fiber lasers do not have these problems because they do not require sensitive optics for operation due to the laser beam emitted from the fiber’s interior side.
High reliability and tunable beam quality
Fiber lasers also provide high reliability due to the high-quality laser beam of high quality. The laser beam that is emitted from the fiber’s inner core is straight and ultra-focused. Also, it is possible to tune the laser beam.
The power of fiber laser systems is also high-quality; however, it is easy to cool despite the high power output and intensity. Fiber lasers turn 70%-80% of the power generated, resulting in high efficiency.
