Pulsed laser diode drivers? | Laser Pointer Forums - Discuss ...

Is anyone making pulsed drivers for laser diodes or have a good design for one? Spec sheets often rate a 90mW CW 650nm diode much higher in pulsed mode, eg typically something like 200-250mW. Now, unless this description is misleading, 250mW pulsed (at however many Mhz) means 250mW true power, i.e. 0.25Watts/second on average at high rep rate.

Pulsed laser diode driver - how it works? | Physics Forums

When S1 is open, the capacitor Cpfn charges by the high voltage input, HV_IN, through the clamping diodes D1 and D2. The output laser diode is reverse biased in this case, so no current flows through it. When S1 is closed, D1, D2 and the output diode are effectively connected in parallel with the capacitor Cpfn.

An Introduction to Pulsed-Current Laser Diode Drivers

For the purposes of this discussion, we define a pulsed-current driver as an electronic module or instrument that generates constant-currentpulses. (A voltage pulser, which generates constant-voltagepulses, is discussed in another paper.) A current pulser is often used to drive a current-operated semiconductor such as a laser diode or LED.

Laser Diode Driver Circuit Diagram

Laser Diode Driver Circuit. A Laser Diode driver circuit is a circuit which is used to limit the current and then supplies to the Laser Diode, so it can work properly. If we directly connect it to the supply, due to more current it will damage. If current is low then it will not operate, because of not having sufficient power to start. So, a driver circuit is needed to provide a correct value of current by which Laser Diode comes into operating condition.

PULSED LASER DIODE DRIVERS AND METHODS - Crawford, Ian D.

A pulsed current driver is described which is capable of driving very short, high-current pulses into current-driven devices (loads) such as a laser diode. It is desired to provide for a short pulse width that requires a fast fall time. For LIDAR applications, a sharp pulse is desirable for the best range definition.
