Abstract

Studies on beam power behavior in time and laser beam mode structures of laser diodes/LEDs used in low level laser therapy (LLLT) were performed. Two laser diodes with cw emission in red at 635nm, a cw laser diode emitting in IR at 904nm and 2 LEDs which emit radiation at 904nm, respectively 650nm were analyzed from the point of view of the beam power, 3D, 2D distributions and the variation of radiation intensity in time. A laser beam analyzers, model LBA-100 was used for laser beam profile studies. The time behaviors of the lasers/LEDs beams intensity were achieved with a LASERSTAR energy meter, OPHIR OPTRONICS. These studies are very useful for establishing the appropriate irradiation doses and procedure for LLLT.
