DC laser drivers are electronic modules designed for driving diode lasers with stable, low noise, and constant current. Some laser drivers are designed to achieve high efficiency at high output current, while others emphasize at low output noise. Most laser drivers have one or two conrol loops but one loop is for driving the laser, and the 2nd loop is for protection purpose. However, some laser drivers have dual loop, both of them can be used for controlling the laser. Therefore, our diode laser drivers are catagorized into three catagories: High Efficiency Laser Driver, Low Noise Laser Driver, and Dual Loop Laser Driver.
