Beam waveform flexibility. According to the specific application, the fiber laser can choose single-mode or multi-mode output mode. For cutting very thin materials or applications requiring a small spot size, single mode will be a suitable choice. However, most high-power applications will use flat-top or multimode mode.
The aerospace industry has proven that holes drilled with fiber laser pointer can achieve consistent flow characteristics. This is due to the improved laser output and the repeatability of the flat-top beam waveform. Using a fiber laser, the taper of the drilled hole is smaller under the shape of a flat-top beam.
Whether it is percussion drilling or ring-cut drilling, the flat-top beam shape usually results in a smaller taper. Compared to percussion drilling, the additional advantage of ring-cut drilling is that the recast layer is smaller. Fiber lasers do not use thermal lenses, and the spot size remains constant and does not change with power increase or decrease.
The combination of the advantages of single-mode high power density, high pulse energy, high peak power, and high repetition rate enables a wide range of materials including metals, silicon, alumina, sapphire, and glass to achieve high-throughput laser micromachining. Fiber laser technology can achieve very high power in very small packages. This is very attractive to most companies, because the reduction in laser footprint in turn leads to a reduction in the overall integrated system footprint required for a given laser process. Global companies seem to be always looking for ways to fill more in less space, and the low footprint of fiber lasers can achieve this.
Not only does the resonator of the optical fiber green laser pointer have a long and continuous optical fiber, the light beam is also transmitted to the workpiece by operating the optical fiber. No need to calibrate, maintain and replace free-space optics or lenses. The operating fiber is equipped with a quick disconnect connector. If the fiber needs to be replaced, no beam calibration is required.
