Difference between YAG and Fiber laser

What are the Differences Between YAG Lasers and Fiber Lasers?

At first,to learn why fiber lasers are a better option for your company, it’s best to first understand the differences between these technologies:

YAG Lasers

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.

Though customers still utilize YAG lasers in manufacturing, this laser design is becoming obsolete because the bulbs have a short life and require frequent replacement. They are inefficient and create a large amount of heat, therefore requiring water cooling measures. These problems make the flash lamp/YAG laser very maintenance intensive.

Fiber Lasers

Fiber 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:

• Firstly,Highest beam quality
• Secondly,Air cooled with high ambient air temperature operating capabilities
• Thirdly,Very efficient with low power consumption
• Fourthly,Longest diode life (Up to 100,000 hours)
• Fifthly,Extended warranties over other technologies (TYKMA Electrox 3-year warranty)
• Sixthly,MOPA design of TYKMA Electrox fibers allows for maximum application flexibility
• Seventhly,High peak power and long pulse durations are good for high-speed aggressive marking and deep engraving applications
• Finally,Easy to integrate and service
