Difference between fiber laser cutting machine and YAG laser cutting machine

Cutting machine are widely used in the sheet metal industry, this article will compare various advantages and disadvantages between fiber laser cutting machine and YAG laser cutting machine

 

1. Fiber laser has significant operation and maintenance.

2.Scope of work: optical fiber not only contains the YAG laser cutting speed and area, has better performance on the cutting quality;

3. Fiber laser cutting function in small power can achieve the effect of high power, reduce the cost of the cutting, with low energy consumption, achieve high efficiency.

4.The main advantage of the existence of its optical fiber cutting machine transmission medium and light; optical fiber laser diode as a light source in the optical, fiber as the transmission medium, with no loss of light energy transmitted to the laser cutting head.

Because of fiber cutting machine has such advantages, industry demand for its constantly improve, in demanding higher industry to obtain a very good application, has realized the real fine cutting. Completely replace the traditional laser cutting machine.

Fiber Laser Nd: YAG Laser
Reliability 50,000 -100,000 hours 500 – 1,000 hours (lamp-pumped)

10,000 – 20,000 hours (diode-pumped)

Power Consumption 170W per hour 6kW per hour
Maintenance ·   No maintenance

·   No consumables

·   No cleaning or aligning of mirrors

·   No filters (chiller)

·   No aligning of beam path

·      Optical path requires frequent adjustments to optimize power output

·      Periodic replacement of flash lamps, diode packs and solid state crystals

·      Diode pack maintenance requires factory-trained personnel and extended down time

·      Cleaning, replacement and aligning of laser mirrors

Power Efficiency Up to 50% 2 -3% (0.2% with 3x Nd:YAG)
Beam Quality Round, concentric

Near M2 = 1 (<1.05)

No symmetric on both sizes

Inferior M2

Spot Size 50% smaller than Nd:YAG spot size

Requires less power to achieve the same result

Significantly larger than the fiber laser

Requires more lasing power to achieve the same result

Optical Path/Beam Path Flexible cable

Up to 50m

Mirrors, Optical Path

Loss of beam quality and significant power drop-off with fiber delivery scan head system

Cooling Air cooled De-ionized (DI) water
Size 19” rack mount unit Large footprint
Chiller No chiller necessary up to 200W, Q-switched (pulsed) or CW 30X Watt to laser output power (replacement required every 1- 2 years)
