In the view of the laser therapy of acupuncture with pulsed laser, we study a semiconductor laser diode driving circuit and a new design of the optical lens system. This paper devises a new type of lithium battery powered medical pulsed laser with the advantages of portable. We describe the basic principle of the pulse signal modulation circuit for LD, and illuminate the design method of the optical lens system which adjusts the lens system and circuit parameter to change the laser power density. This type of device is applicable to the therapy that low intensive laser irradiates directly on the acupuncture point, and has certain significance to the application of laser in clinical medicine.
