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.
Transitioning to Fiber Laser: Essential Components
For those considering making the switch, here's a list of parts you'd need:
| Image | Part/Component | Description |
|---|---|---|
 |
Laser Power | Fundamental for the operation of the fiber laser. |
 |
Water Chiller | Dual temperature water chillers designed especially for cooling 1000W fiber lasers. |
 |
Drag Chain | Essential for mechanical operations. |
 |
Z-axis tracking system and software | Helps in the precise movement and tracking during operations. |
 |
Laser Cutting Head | Auto-focus laser cutting head designed for metal cutting with 1000w and 1500w fiber optic laser sources. |
 |
Z-axis sliding table | Assists in up and down movements during operations. |
 |
Gas System | Necessary for certain laser cutting operations that require gas assistance. |
 |
Other Parts | Miscellaneous parts that might be required based on specific operational needs. |
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
