For enterprises, there are many reasons for using quasi-continuous fiber lasers. For example, fiber lasers combine the advantages of a pulse laser drilling and welding and the cutting capacity of a CO2 laser. The combination of these processing capabilities cannot be achieved with traditional technology, so in the past many companies have both CO2 lasers and laser pointer to cope with a wider range of processing needs and applications. Fiber lasers can work in pulsed and continuous modes, so a single laser can handle a variety of processing tasks that previously required two different lasers.
Today, tens of thousands of fiber lasers are being used in countless industries and fields around the clock. In many material processing applications, these laser systems are rapidly replacing the role of lasers and CO2 lasers. In addition, companies are replacing old lasers on existing production lines, while ensuring that the loss of production shutdowns of their existing equipment is minimized.
Why choose fiber lasers? Quasi-continuous fiber lasers are now part of modern manufacturing plants. This type of laser can work in both continuous and high peak power pulse modes. Unlike traditional continuous lasers, the peak and average power are always the same in the modulation mode, while the peak power of the laser in pulse mode is 10 times higher than the average power. Therefore, it is possible to generate microsecond and millisecond pulses with high energy at a repetition frequency from several tens of hertz to several thousand hertz, and the average power and the peak power of several kilowatts can be realized.
A typical fiber laser resonator. It is a solid-state laser equipped with a continuous optical fiber that is permanently connected to prevent dust and dirt. It does not contain moving parts or free-space lenses. The resonator requires no adjustment, no consumables, and no maintenance. These features help to ensure the performance of the laser, thereby maintaining its stability and consistency over many years of operation. In the absence of consumable parts, the output power is not attenuated, the beam quality of the green laser pointer output remains unchanged, and regular adjustments by technicians are no longer required to maintain the normal operation of the laser processing system.
The electro-optical conversion efficiency refers to the efficiency index that the laser converts the consumed electrical energy into optical output power. The solid-state fiber resonator of the fiber laser can effectively dissipate heat based on its large surface area / volume ratio, so that it can achieve an electro-optic conversion efficiency of greater than 30% under a passive cooling scheme. Since fiber lasers can provide ten-fold increments compared to other laser systems, it is not difficult to understand why the acceptance of such lasers has expanded rapidly in recent years.
