The PC0-7120 is a pulsed-laser diode driver module featuring high-speed performance in a flexible mounting configurations and robust design package. It is designed to offer minimized cost design and is mounted to an aluminum heat spreader to provide cooling needed for the switching transistor.
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 drivers allow for the modulation of a laser diode using by varying the laser drive current.
An improved driver circuit has a pre-charge path comprising one or more inductive elements and a fire path comprising the diode. Switches in the driver circuit are controlled with predefined states during different intervals to pre-charge current in the one or more inductive elements prior to flowing current through the fire path to pulse the ...

Re: Pulsed Mode Driver circuit for SONY DVD 16x La In pulse mode, the diode PEAks at about 250 mW - You will need a Joule meter to measure this. THe Average output will be around 80 mW. Fine for experimenting but not POPBANGSMOKE.... We here add heatsinking and push the little suckers to the max CW output.
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.

The SPL PLxx type pulsed laser diode has a plastic package. The pulsed laser diode is operated by directly applying the forward current pulses to the anode and cathode pins. The cathode pin is the short one. To generate short (up to 100 ns) and high-amp (up to 75 A) current pulses a suited laser diode driver is necessary. Valid for: SPL PLxx
A pulsed laser diode driver is a voltage controlled constant current source which is designed to deliver a repeatable set of current pulses at a set output level over user defined time intervals.

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. 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.

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.
