Benefits of Fiber vs. YAG Lasers
|
|||||||||||||||||||||||||||||||||
|
|
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)
