Questions:
1. The average power of this light source is only 2W, why can it easily cut a 0.16mm thick metal business card with such a small power?
Answer: The main reason why laser can mark metal is that it has high peak power. This is the main and most overlooked point.
We take a 50W side-pumped semiconductor laser as an example: at 10KHz, the average power is only less than 20 watts, and the pulse width is 100ns;
Peak power=average power/(frequency×pulse width)=20W/(10KHz×100ns)=20KW
While the end-pumped laser light source of MPL-N-1064, at 10KHz, the average power is 2 watts, but the pulse width is only 7ns.
Peak power = average power / (frequency × pulse width) = 2W / (10KHz × 7ns) = 30KW
This shows that, in the case of conventional processing, the 2-watt end-pumped laser's peak power is higher than that of the side-pumped water-cooled lasers, and the cost-effective advantage of the side-pumped water-cooled lasers is even higher than the Side pump water cooler.
2. Fiber lasers are constrained by the quality and structure of the device, the failure rate is always high. How does this end-pumped laser source achieve high lifetime?
Answer: The failure rate of fiber lasers has always been one of the headaches of major manufacturers. The laser light source marking effect is fine, in the vast majority of occasions has been able to completely replace the fiber laser. The laser adopts a fully closed optical path design, environmental adaptability, resonant cavity design by a team of engineers with more than ten years of experience, complemented by excellent workmanship, to achieve two consecutive years of repair rate are less than 3%.
3. What are the characteristics of an end-pumped laser?
A: 1. High peak power of 30KW, which is twice that of a 50W semiconductor water-cooled laser.
2. Narrow pulse width, more favorable to the accumulation of high peak energy.
3. High laser frequency to achieve the perfect combination of spot density and processing speed.
4. Good beam quality, M-squared factor less than 1.3, high spot roundness.
5. Stable pulse spike sequence and good spot consistency.
