Circuit provides laser diode control: 09/19/2002  EDN - Design Ideas /  Laser diodes are sensitive to ESD, rapid turn-on currents, and over voltage conditions. To address those problems, the simple laser-diode controller in Figure 1 has several functions. The first part of the circuit comprises an 8.2V zener diode, D1 that forms the heart of a constant-voltage source for the laser diode..
