With Reviewed 100% Correct Detailed Answers
Guaranteed Pass!!Current Update
1. What is Photobiomodulation (PBM)? - ANSWER A term adopted in 2005
by the North American Association of Laser Therapy (NAALT) as the
therapeutic utilization of light
2. How do surgical lasers cut and destroy tissue? - ANSWER Excess heating
3. What is the effect of a surgical laser? - ANSWER Photothermal
4. What are two benefits of surgical lasers? - ANSWER - takes less time and
less money than surgery
- seals BV's so less bleeding
5. What are the risks of surgical lasers? - ANSWER hemorrhage, infection,
perforation of organs
6. What is the main benefit of a therapeutic laser? - ANSWER stimulates
cell function
,7. What are the effects of therapeutic laser? - ANSWER Photochemical and
Photobiostimulative
**NOT thermal like surgical lasers
8. What does therapeutic laser (photon) cause in cells which leads to
normalization of cell function and therefore pain relief/quicker healing? -
ANSWER increased ATP production
9. What cells are more affected by Laser Therapy than normal cells? - ANSWER
damaged and compromised
10.What are the three properties of laser light? - ANSWER 1.
Monochromatic
2. Coherent
3. Collimated
11.Define Monochromatic - ANSWER one specific wavelength (measured in
NANOMETERS) therefore one color
12.Define Coherent - ANSWER waves are synchronized in space and time
13.Define Collimated - ANSWER Narrow beam of light in a specific direction
, 14.What is LED? - ANSWER Light Emitting Diodes
15.LEDs are not ______, therefore are not true laser therapy devices - ANSWER
not COHERENT
16.Jan Tuner did 13 separate studies on what? - ANSWER Laser vs. LED.
Laser wins every time!
17.Define the EM spectrum - ANSWER Entire range of light radiation from
gamma rays to radio waves
18.What is the range of visible light? - ANSWER 400nm to 700 nm
19.What type of light is K-Laser? - ANSWER visible AND infrared (invisible)
20.K-series lasers have how many diodes with how many separate
wavelengths? - ANSWER 3 diodes
3 separate wavelengths
8 or 12 Watts max CW power
21.What are the 3 diodes of K-Series Lasers? - ANSWER 1. Aiming beam-
660 nm
2. Treatment beam #1- 800 nm
3. Treatment beam #2- 970 nm
