Most non-fiber lasers must use a large water-cooled machine for water cooling, which requires regular daily maintenance. The deionized filter element, particle filter and deionized water must be replaced regularly (usually every six months) to prevent water pollution. If the quality of the cooling water cannot be guaranteed and maintained, the laser pointer efficiency will be reduced, and the optical components may also be damaged.
Therefore, the company must store the flash lamp, deionization filter, particle filter and deionized water, and arrange regular downtime to maintain the laser. However, fiber lasers eliminate these consumption and maintenance problems; there is no need to replace optical components or flash lamps, and maintenance and shutdown issues related to these problems are also eliminated.
Many fiber lasers use air cooling and do not require a water cooler. Fiber lasers with peak powers up to 4.5kW can provide air cooling without the need for water coolers. Lasers using traditional technology usually require a warm-up time to stabilize the resonator and ensure that the correct laser power is continuously delivered to the workpiece.
When not processing, these green laser pointer usually operate in standby mode, and only the lamp pump continues to blink to ensure the stability of the resonator. In this case, even if the laser is not used to produce parts, the life span and lifetime of the flash lamp are always passing.
In contrast, fiber lasers are pumped by solid-state diodes, so they can be completely turned off when the laser is not in use, and the correct laser power can be obtained without warm-up time. Because the fiber laser is only turned on when the process is ready, higher uptime, electrical efficiency, and throughput can be achieved.
