Here is the schematic diagram of the circuit: A Howland current pump with a current booster is used as the basic of this laser diode driver. Q1 is used as the current booster on the output of a R-R CMOS OPA350 op amp (U2). Voltage drop across a shunt resistor (RSHUNT) in series with the laser diode is measured differentially to sense the current.

Laser diode driver circuit diagram

The block diagram in Figure 1 shows a very basic laser diode driver (or sometimes known as a laser diode power supply). Each symbol is defined in the table below. Each section is described in detail below. Laser diode drivers vary widely in feature set and performance. Circuit Diagram Working Explanation The heart of the circuit is an LM317 IC that acts as a current limiter. The circuit is using a 200 ohms variable resistor to adjust the output current. Since. a laser diode receives damage on the accidental reverse connection of the battery, therefore a 1N4007 diode saves the laser diode from this problem. A low power driver is roughly defined as 1 mA to 5 Amps. A high power laser diode driver is 5 Amps and up to 100’s of Amps in a CW mode. Their are kW level drivers available in pulsed and QCW mode versions. These are by no means standards, just a generalization based on the author’s experience in the laser diode controller world.
