This product offers a low-power portable laser system (with a power of less than 500 mW) with the ability to use a rechargeable battery. The device is designed to be used for low-power laser therapy applications in medicine, dentistry and veterinary medicine, and can be used in research as well. The most important innovation of this product compared to other models in the world, is that this device has provided the ability to use different wavelengths of diode lasers in the range of 400 to 1000 nm with only one control system and using different heads. Another unique feature of this device is its control system, which has the ability to intelligently identify different laser heads and automatically adjusts the laser output power for each head. The merit of adjusting the irradiation time in the control system, allows the user to use different doses of laser therapy in the treatment. Offering different laser wavelengths in one device made this system very useful for studying optical properties of different materials (in various fields including physics, chemistry, medicine, electricity, and materials science).
