Laser irradiation for the experimental set-up.
| Wavelength (nm) |
Set-up's energy (laser device) (W) |
Coming down energy (3 mm) |
Time | Fluence | Mode | |
|---|---|---|---|---|---|---|
| Standard hand-piece | 980 | 1.1 | 0.90 ± 0.02 W* | 60 s | 54.2 ± 1.0 J/cm2 | CW |
| Flat-top hand-piece | 980 | 1 | 0.93 ± 0.02 W* | 60 s | 55.8 ± 1.2 J/cm2 | CW |
| Power density (W/cm2) | Time for irradiation (s) | No. of irradiation (for 2 weeks) | Total dose (J) | |||
| Standard hand-piece | 1.1 | 60 | Once per week | 110 | ||
| Flat-top hand-piece | 1 | 60 | Once per week | 110 | ||
| Standard hand-piece | 1.1 | 60 | Three times per week | 330 | ||
| Flat-top hand-piece | 1 | 60 | Three times per week | 330 | ||
