Comparison Between Nd: YAG and Fiber Laser

1. Introduction

While Nd: YAG can be considered as an old generation laser, the Fiber Laser represents the cutting-edge technology. Here are some comparative insights:

2. Laser Light Efficiency

  • Nd: YAG Laser: Has an energy efficiency level of around 4%. Requires a significant water cooler system and comes with a high electricity cost.

  • Fiber Laser: Offers up to 35% conversion efficiency. A small chiller suffices for cooling.

3. Lifespan

  • Nd: YAG Laser: Lamp-pumped lifespan is around 1000hrs, and diode-pumped lifespan ranges between 10,000-20,000hrs.

  • Fiber Laser: The laser source lifespan can reach up to 100,000hrs.

4. Size

  • Nd: YAG Laser: Known for its bulky size.

  • Fiber Laser: Compact and can easily fit inside cutting machines.

5. Maintenance

  • Nd: YAG Laser: Requires regular cleaning and mirror alignment.

  • Fiber Laser: Maintenance-free, with only occasional need for protective lens and nozzle replacements.

6. Cost

  • Nd: YAG Laser: Initially, it might seem cheaper, but when accounting for the running cost and maintenance, it becomes more expensive in the long run.

  • Fiber Laser: Though a bit pricier at the onset, it proves to be more cost-effective considering the lower running and maintenance costs.

Why Opt for Retrofitting?

Retrofitting the old YAG system, while preserving its original dynamic performance, offers a solution to the problems associated with the aging and maintenance of YAG lasers.

Advantages:

  • Improved cutting speed (3 to 4 times faster)
  • Significant reduction in power consumption and consumable costs
  • Easy and low-cost maintenance
