Abstract

Low level laser therapy has various therapy effects, This paper performed the basic study for fabricating the low level laser therapy apparatus, and one of the goals of this paper was to make this apparatus used handily. The apparatus has been fabricated using the laser diode and microprocessor unit. The apparatus used a 660nm, 785nm and 850nm laser diode for laser medical therapy and was designed for a pulse width modulation type to increase stimulation effects. To raise the stimulus effect of the human body, the optical irradiation frequency could be set up. In result, the $1{\sim}10\;Hz$ irradiation frequency could be controlled stably.
