Design and test of fast laser driver circuits
Websuitably low inductance in the laser circuit. To this end, in discrete driver circuits a capacitor with a high voltage of up to 50 V is usually simply charged and then discharged into the laser diode with a fast transistor switch. Here, the energy stored in the capacitor determines the intensity of the light pulse, the shape of WebAuto Power Control drive circuit example for P type LDs V1 V1 V2 P type When LD is turned on, monitor current (Im) flows. Im is proportional to the amount of light. And …
