A driver circuit is a circuit which can limit appropriately the amount of current being fed into the laser diode so that it can function correctly.

Diode laser circuit diagram. A cheap laser diode is the first thing you need to make your very own high powered laser capable of burning paper1000s of laser diodes have died due to the lack of proper drivers a laser diode is current hungry it will take all it can get. 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. It is better to first disconnect the power supply or battery from the driver circuit and short the pins of the 10uf capacitor before connecting the laser diode with the circuit.
