The article presents differences between the effects of low level and high power laser therapy.
Table of different therapeutic effects caused by biostimulation and high power laser therapy.

Thanks to the wide spectrum of possible therapeutic results, the high power and biostimulating laser therapy can be used to treat disorders in plenty of the medical areas, including:
- sports medicine,
- orthopedics,
- rheumatology,
- neurology,
- dermatology,
- ENT,
- dentistry.
Comparison of parameters between devices dedicated for low level and high power laser therapy on the basis of PhysioGo.Lite Laser and Polaris HPS units:
| Parameter: | Low Level Laser Therapy: | High Power Laser Therapy: |
| Wavelength: | R: 650 nm, 660 nm,IR: 808 nm | 808 nm and 980 nm |
| Emission modes: | continuous, pulse | continuous, pulse |
| Pulse mode shape: | rectangular | rectangular, triangular (superpulse) |
| Pulse duty factor: | 25%, 50%, 75% | 1 – 90 %, |
| Pulse time duration: | 50 us | 50 us |
| Pulse mode frequency: | 1 – 5 000 Hz | 1 – 10 000 Hz |
| Peak output power: | depending on the probe selected
max 400 mW |
up to 18 W |
| Average output power: | depending on the probe selected
up to 400 mW |
up to 10 W |
| Treatment timer: | 100 min | do 100 min |
| Power supply: | 100-24 V, 50/60 Hz | 230 V, 50 – 60 Hz, 130 W 150 VA |
| Dimensions: | 30 x 23 x 11 cm | 36,1 x 30,4 x 15,1 cm |
| Weight: | 3 kg | 6 kg |
Conclusions:
- High power laser can significantly accelerate the regeneration processes, and therefore the treatment time is shorter.
- High power laser penetrates much deeper into the tissues thanks to an additional modification of the impulse mode (superpulse).
- High power laser uses two wavelengths during the treatment, which allows to obtain deep tissue biostimulation effects as well as to achieve thermal effect.
