K-LASER CLASS IV Certification questions with verified solutions

What does LASER stand for? Light Amplification by Stimulated Emission of Radiation What is Laser? Any device which can be made to produce or amplify electromagnetic radiation in wavelengths ranging from 180 nm to 1mm by the process of controlled stimulated emission Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:15 Full screen Brainpower Read More Laser energy is considered a stream of tiny particles of light called _______. Photons Laser energy is absorbed by specialized receptors on the mitochondria called _________. Chromophores How long has laser been used? Over 40 years in Russia, Europe, etc. When was the first therapy laser cleared by the FDA in the US? 2002 When did Class IV lasers receive FDA clearance, and how long have they been used in Europe? 2003; over 10 years When was the first K-laser model (called the D-series) cleared by the FDA? March 2005 Who developed the first laser theory in 1916? Einstein Who developed the first working laser in 1960? Maiman Who is Endre Mester? The father of low level laser therapy In the late 1960's, what did Endre Mester's device do? It was made to attempt to cure cancer in rats but it was unsuccessful due to low doses. It did heal superficial conditions faster. What is Photobiomodulation (PBM)? A term adopted in 2005 by the North American Association of Laser Therapy (NAALT) as the therapeutic utilization of light How do surgical lasers cut and destroy tissue? Excess heating What is the effect of a surgical laser? Photothermal What are two benefits of surgical lasers? - takes less time and less money than surgery - seals BV's so less bleeding What are the risks of surgical lasers? hemorrhage, infection, perforation of organs What is the main benefit of a therapeutic laser? stimulates cell function What are the effects of therapeutic laser? Photochemical and Photobiostimulative **NOT thermal like surgical lasers What does therapeutic laser (photon) cause in cells which leads to normalization of cell function and therefore pain relief/quicker healing? increased ATP production What cells are more affected by Laser Therapy than normal cells? damaged and compromised What are the three properties of laser light? 1. Monochromatic 2. Coherent 3. Collimated Define Monochromatic one specific wavelength (measured in NANOMETERS) therefore one color Define Coherent waves are synchronized in space and time Define Collimated Narrow beam of light in a specific direction What is LED? Light Emitting Diodes LEDs are not ______, therefore are not true laser therapy devices not COHERENT Jan Tuner did 13 separate studies on what? Laser vs. LED. Laser wins every time! Define the EM spectrum Entire range of light radiation from gamma rays to radio waves What is the range of visible light? 400nm to 700 nm What type of light is K-Laser? visible AND infrared (invisible) K-series lasers have how many diodes with how many separate wavelengths? 3 diodes 3 separate wavelengths 8 or 12 Watts max CW power What are the 3 diodes of K-Series Lasers? 1. Aiming beam- 660 nm 2. Treatment beam #1- 800 nm 3. Treatment beam #2- 970 nm What are the specifications for the K-series Aiming beam? It is 660 nm. It is only 3 milliwatts, therefore visible for guidance and to assess patency of the fiber optic cable
