| Sealed Slab Laser |
Fast-Axial Flow Laser |
| No gas consumption. |
Gas consumption is very high |
| Electricity consumption is low. |
Electricity consumption is very high |
| Slab laser has no running component! Only very little power consumption in stand-by mode as here is no gas circulation |
There is running component! Very high power consumption in stand-by mode because of gas circulation |
| There is no turbine and discharge tubes, so ultimately Customer's maintenance cost will be low. |
There is turbine and discharge tubes, so ultimately customer's maintenance cost will be high |
| K-Number/ Beam quality is good. K≥0.9 |
K-Number/ Beam quality is inferior. K≥0.6≈0.8 |
| Cooling water requirement is less |
Cooling water requirement is relatively high, resulting in higher energy consumption |
| No Cleaning or replacement is necessary because there is no consumable optics in slab laser |
It's spending a lot of time and money to clean and replace the optics |
| As no gas is changed, there is no chance of resonator contamination. |
As gas bottle are changed, higher probability of resonator contamination |
| Saves precious floor space due to compact design |
Consumes higher floor space, resulting in higher total cost of ownership |
