Comparison between YAG and Fiber Laser – Jennifer
It is the time to upgrade your marking system.
XT LASER, provide rich series products fiber laser marking & cutting machine series. And while you may be initially searching for a YAG laser now, what you’ll find is that you really need a fiber laser system instead. With the advances in the industry, YAG technology has become out of style, and the best way to improve your facility’s marking capabilities is by investing in fiber lasers.
The difference between YAG & FIBER LASER
Although fiber’s purchase cost is a bit higher than fiber, it’s after-sales maintenance cost will be much higher than fiber’s;
Due to YAG’S complex and instable light path;
The lighting tube and crystal in YAG, need to be changed regularly, which is up to $1,500 every time;
2.Photoelectric conversion rate
YAG’s photoelectric conversion rate is only 2%; while fiber’s will reach to 25%;
YAG’s power consumption is 2 times than fiber’s;
Taking 1000w machine as an example, for 1000W YAG, it’s power consumption is up to 15 kilowatt/ hour; while Fiber’s is the 15-16 kilowatt / hour merely;
4. Cutting precision
YAG’s cutting presion is lower than Fiber’s;
5. Cutting speed
YAG’s cutting speed is lower than Fiber’s;
YAG’S cutting effect is also lower than Fiber’s; the materials cut by YAG, need secondary processing, which will reduce the producing effciency;
6. Output power
YAG’ soutput power is 500w/600w; while Fiber’s are 400w/500w/1000w/2000w;
7. Flexible manufacturing ability
YAG’s flexible manufacturer ability is lower than Fiber’s;
These lasers are also known as flash lamp or lamp-pumped lasers, as they utilize a lamp (bulb) as a pumping mechanism and a YAG crystal as the gain medium. Both reside in an optical resonator, typically a gold-plated cavity, which provides reflection of the light and helps with the process of creating the laser light.
iber lasers utilize semiconductor diodes as the pumping mechanism and a doped fiber optic cable as the gain medium. In a fiber laser, the doped fiber optic serves as the resonator. Fiber lasers are the most reliable laser technology available today for material processing applications, offering the best combination of reliability and marking capability.
The many pros of a fiber laser include:
- Highest beam quality
- Air cooled with high ambient air temperature operating capabilities
- Very efficient with low power consumption
- Longest diode life (Up to 100,000 hours)
- Extended warranties over other technologies (TYKMA Electrox 3-year warranty)
- MOPA design of TYKMA Electrox fibers allows for maximum application flexibility
- High peak power and long pulse durations are good for high-speed aggressive marking and deep engraving applications
- Easy to integrate and service
